Splits //ops/nixos into:
* //ops/nixos.nix - utility functions for building systems
* //ops/machines - shared machine definitions (read by readTree)
* //ops/modules - shared NixOS modules (skipped by readTree)
This simplifies working with the configuration fixpoint in whitby, and
is overall a bit more in line with how NixOS systems in user folders
currently work.

Please read b/108 to make sense of this.
This gets rid of the explicit list of exposed packages from nixpkgs,
and instead makes the entire package set available at
`third_party.nixpkgs`.
To accommodate this, a LOT of things have to be very slightly shuffled
around. Some of this was done in already submitted CLs, but this
change is unfortunately still quite noisy.
Pay extra attention to:
* overlay-like functionality that was partially moved to actual
overlays (partially as in, the minimum required to get a green
build)
* modified uses of the package set path, esp. in NixOS systems
Special notes:
* xanthous has been disabled in CI because of issues with the Haskell
overlay
* //third_party/nix has been disabled because of other unclear
dependency issues
Both of these will be tackled in a followup CL.

In preparation for the solution of b/108, we need to consistently use
`depot.third_party` for packages that are only packed in the TVL depot
and `pkgs` for things that come from nixpkgs.
This commit cleans up a huge chunk of these uses in //ops

For the moment I've opted to not import all of the other things we'd
usually provide to things imports via readTree, because I think it's a
bit dangerous to accidentally overwrite things like NixOS' notion of
"lib" with our own version.
So for the moment, baseModule provides only "depot".

Add the depot.nix module and a depot config option to all nixos system
derivations that're build through the `bin/rebuild-system` machinery.
I can't imagine a scenario where we wouldn't want this level of
integration.

We have naturally evolved a distinction between logical and physical
targets.
Physical targets are those which correspond directly to a tree
location on disk and can be built with `-A path.to.files`, while
logical targets are those that are exported from within an expression
but do not have a corresponding file on disk.
This change adds support for exporting logical targets from any tree
location by adding a `meta.targets` attribute containing keys into
itself, which will be consumed by the CI target gathering logic and
included in the generated pipeline.
Note that the labels for subtargets are syntactically different to
emphasise that they do not correspond to a file location. For example,
this change enables 'ops.nixos.whitbySystem' as a subtarget, which is
labeled in CI as `ops/nixos:whitbySystem`.

Create the pipeline by outputting a file that contains nix-build
invocations for each target's *derivation path*.
Each invocation has a generated Nix expression passed to it with `-E`
which fetches the correct target from the tree while correctly
handling targets with strange characters (such as in Go-packages).
This makes it possible to run target-level granular pipelines. We're
getting somewhere!

This adds a first crack at one idea for a generic, non-user-specific
rebuild-system script to ops.nixos.rebuild-system. The idea here is that
we enumerate all the nixos systems stored in the monorepo (similarly to
what we do for ci-builds right now) then search through them by hostname
to find the one matching the hostname of the current system, which is an
attempt at a more generic version of tazjin's rebuilder script which
does the same thing but with an explicit case block.
As a caveat, it feels like there's a slight possibility that this way of
finding systems is going to get slow to evaluate - on my system it feels
fine but if it grows out of hand it's probably feasible to just bake
this into the built script as a dynamically generated case statement.

NixOS modules move one level up because it's unlikely that //ops/nixos
will contain actual systems at this point (they're user-specific).
This is the first users folder, so it is also added to the root
readTree invocation for the repository.

Currently since there is only one host this isn't particularly
