spec.py: make parser select from environment (#30276)
The parser is already committing a crime of querying the database for
specs when it encounters a `/hash`. It's helpful, but unfortunately not
helpful when trying to install a specific spec in an environment by
hash. Therefore, consider the environment first, then the database.

This allows the following:

```console
$ spack -e . concretize
==> Starting concretization
==> Environment concretized in 0.27 seconds.
==> Concretized diffutils
 -   7vangk4  diffutils@3.8%gcc@10.3.0 arch=linux-ubuntu20.04-zen2
 -   hyb7ehx      ^libiconv@1.16%gcc@10.3.0 libs=shared,static arch=linux-ubuntu20.04-zen2

$ spack -e . install /hyb7ehx
==> Installing libiconv-1.16-hyb7ehxxyqqp2hiw56bzm5ampkw6cxws
...
==> libiconv: Successfully installed libiconv-1.16-hyb7ehxxyqqp2hiw56bzm5ampkw6cxws
