Closes#334Closes#626
This is loosely based on upstream PR#10877[1], but heavily changed to
use the graph logic from `nix why-depends`.
`precise` is `false` here since the out-path of the drv being built
isn't registered yet, so the path accessor cannot scan through files
yet.
Example output (from an openssh build with `pcsclite.lib` & `glibc` in
`disallowedRequisites`):
error: output '/nix/store/hr8lmmjmd1jk6s3p5ymggyk4am7n2lmb-openssh-10.0p2' is not allowed to refer to the following paths:
/nix/store/p6r5awz3ywrz66symnrn0xb85xzmcysf-pcsclite-2.3.0-lib
/nix/store/q4wq65gl3r8fy746v9bbwgx4gzn0r2kl-glibc-2.40-66
Shown below are chains that lead to the forbidden path(s).

I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests
- Concepts is harder to understand, the documentation makes a good
unit vs functional vs integration distinction, but when the
integration tests are just two subdirs within `tests/` this is not
clear.
- Source filtering in the `flake.nix` is more complex. We need to
filter out some of the dirs from `tests/`, rather than simply pick
the dirs we want and take all of them. This is a good sign the
structure of what we are trying to do is not matching the structure
of the files.
With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests
functional/
installer/
nixos/
```
