sd-netlink: don't treat type_system->count==0 as invalid
Empty type-systems are just fine. Avoid the nasty hack in union-type-systems that treat empty type-systems as invalid. Instead check for the actual types-array and make sure it's non-NULL (which is even true for empty type-systems, due to "empty_types" array).
