remove nom.patch, change filterSource to path

nom.patch gets pulled in to the modules unless filtering is set up, but
we're not building custom nixos-rebuild anymore (and haven't for a
while)

migrates to builtins.path over builtins.filterSource since the semantics
seem a bit nicer

Removes all the filtering on the directory as we likely don't need it
