6813598c17 feat(nix/utils): add onlyDrvPath to get the drvPath w/o the outputs
I want to use this utility in a deploy script where the .drv is
nix-copy-closure-d to a remote host and realized there. Consequently it
doesn't make sense that the local deploy script depends on the
derivation's outputs which drvPath does by default.

This also came up when working on //nix/buildkite, although we didn't
end up using it there.

a6367b4bdc fix(nix/utils): remove predicates based on symlink heuristic
Due to [nix#6579] the heuristic which allowed us to determine if a
symlink points to a directory is not reliable – if restrict-eval is
enabled it _will_ return wrong results. Until upstream resolves
this (and we backport the patch) it is probably best to not expose this
functionality at all.

aa122cbae7 style: format entire depot with nixpkgs-fmt
This CL can be used to compare the style of nixpkgs-fmt against other
formatters (nixpkgs, alejandra).

887ac4d3d4 feat(nix/utils): handle toString-able sets produced by builtins.path
When preparing cl/4381 I noticed that we actually handle this case
properly. depot.nix.utils.storePathName depot.path now works as
expected.

4f1249e46f refactor(readTree): Move 'drvTargets' into readTree
This function is also generally useful for readTree consumers that
have the concept of subtargets.

66fa718ceb feat(nix/utils): expose pathType of symlink target
In order to make readTree import symlinked directories I've been looking
into how to detect if a symlink points to a directory (since this would
allow us to use symlinks for //nix/sparseTree). I've found a hack for
this:

    symlinkPointsToDir = path: isSymlink path &&
      builtins.pathExists (toString path + "/.")

Unfortunately it doesn't seem to be possible to distinguish whether the
symlink target does not exist or is a regular file.

Since it's possible, I thought might as well add this to
`pathType`. To make returning the extra information workable, I've
elected to use the attribute set layout used by `//nix/tag`. This
doesn't require us to depend anything (as opposed to yants), but gives
us pattern matching (via `nix.tag.match`) and also quite idiomatic
checking of pathTypes:

    pathType ./foo ? file
    (pathType ./foo).symlink or null == "symlink-directory"

Nonexistent paths are encoded like this:

    pathType ./foo ? missing

Of course we can't use this in readTree (since it must be zero
dependency), but we can easily inline this hack at some point.

f88ac5c0b5 feat(nix/utils): add storePathName, a more generic baseNameOf
This is a wrapper around baseNameOf which also can deal with
derivations. Added to //nix/utils since I've found myself introducing an
ad-hoc implementation of this for both //web/bubblegum and //nix/buildC.

5d8490d2fc feat(users/Profpatsch): build attrset members on CI
Setting meta.targets to include all derivations in the different package
sets in Profpatsch's user folder makes them checked by CI until they do
the readTree refactor as promised.

To reduce code duplication we handle this in a simple function which is
exposed from nix.utils which may be a good place for depot specific bits
and bops we accumulate over time.

To get around the issue of too nested sets we perform the following
renames:

* users.Profpatsch.tests gets moved into its own directory
* users.Profpatsch.arglib.netencode now lives in its own file instead of
  the default.nix
* users.Profpatsch.netstring.tests gets moved into its own directory
