Merge #20629: depends: Improve id string robustness

Browse Source 
5200929bfe depends: Include GUIX_ENVIRONMENT in id string (Carl Dong)
4c7d418588 depends: Improve id string robustness (Carl Dong)
b3bdff42b5 build: Proper quoting for var printing targets (Carl Dong)

Pull request description:

  ```
  Environment variables and search paths can drastically effect the
  operation of build tools.

  Include these in our id string to mitigate against false cache hits.
  ```

  Note to builders: This will invalidate all depends output caches in `BASE_CACHE`
