nixos/locate: disable default findutils pruneNames

It doesn't make sense to have a default value for this that's
incompatible with the default locate implementation.  It means that
just doing services.locate.enable = true; generates a warning, even if
you don't care about pruning anything.  So only use the default prune
list if the locate implementation supports it (i.e., isn't findutils).
