Because the passing around of externalArgs only happened in the readTree
instantiation in the repo root default.nix, but not in views/kit/
default.nix, it was not possible to get tvl-kit to instantiate the
bundled nixpkgs with a custom system.
This fixes invocations like
```
tvl-kit = import (sources.tvl-kit) { localSystem = "aarch64-linux"; };
```

This makes CI utility functions available in TVL kit. For now this is
only the Terraform check, but said check has come up in other repos
before so it's useful to centralise here (and we might add more!)

This adds the //nix/lazy-deps tool at //lazy-deps in tvl-kit.
A CI step is added for the kit that uses this to lazily build an
example tool (magrathea).

This function is more generically useful than just for pipeline
construction.
A subsequent commit will use it inside of readTree itself.

This creates a josh workspace called `views/kit` which exports all
dependencies needed by external users of the TVL kit.
The intention of this is to have a single clonable "virtual repo"
which provides everything needed to run a system like TVL, but without
the projects that we develop *in* TVL.
Right now this is limited to the basic Nix code (readTree, pipeline
generation) and things required for Gerrit integration.
The workspace maps depot paths into slightly different (simpler)
locations inside the exported view, to avoid a nested, mostly empty
structure.
Note: This is not an "external API" or some such of depot, it is
simply a convenience for exporting some of our tooling.
