Motivation for this change

Since we select everything as a module, snd_hda_codec_ca0132 is built as
well. DSP loading is not enabled by default, but without it the
soundcard produces timeouts within ALSA and does not emit sound.
Explicitly enable the firmware loading to ensure Soundblaster
Z/Zx/ZxR/Recon devices can be used with NixOS.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

Use tesseract as a source for inspiration - rename default.nix ->
connman.nix and declare build flavors in default.nix .
Due to 9pnet_virtio bugs, /nix is no longer available after
hibernation. It happens to work on x86_64, but not on other
platforms.

Not needed now that Security is propagated via go in NixOS@0bba747
That allows automatic detection of CVEs being fixed (e.g. by vulnix)
