  [lld/mac] reject -undefined warning and -undefined suppress with -twolevel_namespace

See discussion on https://reviews.llvm.org/D93263

-flat_namespace isn't implemented yet, and neither is -undefined dynamic,
so this makes -undefined pretty pointless in lld/MachO for now. But once
we implement -flat_namespace (which we need to do anyways to get check-llvm
to pass with lld as host linker), the code's already there.
