evaluate: only try to replace dummy protocol from link-layer context

Add proto_is_dummy() that returns true for netdev and inet family, the
only two using a dummy link-layer protocol base definition.

Rename supersede_dep() to meta_iiftype_gen_dependency() since this is
generating the implicit meta iiftype check for netdev and inet.

This patch also gets rid of the have->length check. The tests pass fine
without this so I suspect this is superfluos.
