nongnu: broadcom-sta: Use Nixpkgs patch list.

Piggy-back off of the patch list in Nixpkgs instead of maintaining our
own. This should make it easier to keep up to date so there's no need to
advise users to stick with Linux LTS releases any longer.

Though our existing patch list and Nixpkgs' differ the cumulative effect
is exactly the same except for two patches we have that Nix doesn't,
neither of which seem critical:
- broadcom-sta-debian-fix-kernel-warnings.patch
- broadcom-sta-fix_mac_profile_discrepancy.patch

Closes #246

* nongnu/packages/linux.scm (broadcom-sta): Replace patches
with code to fetch them from Nixpkgs.
[arguments]: Replace `linux-lts` with `linux`.
[description]: Remove Linux LTS recommendation.
