feat(gs/system): Init mugwump r/1831

Init the config for mugwump, a NUC that I bought from ncl and which I'm
going to use as a simple home server and ssh bastion box. Since this is
the first time I've set up a server using my nixos config, this also
moves a bunch of desktop (xserver, audio, etc.) related config out of
modules/common.nix and into a new modules/desktop.nix.

Coming soon: nixos-rebuild switch --target, but in the depot!
