build: narrow overly-broad linting exclusions

I started this project using `niv`, which creates `nix/sources.nix`,
which is all I really needed to exclude as it's generated by niv.

Now there's generated code only in `nix/overlays`, so the rest of the
files under `nix/` should be formatted by nixpkgs-fmt and analysed by
statix and deadnix.
