Native: apply ObjCExport virtual adapters from interfaces of supers

Previously they were skipped, and this was an incorrect optimization:
even if super class implements the interface too, this doesn't mean
that virtual adapters provided by that interface are inherited
by non-exported subclass that needs them;
for example, this doesn't happen when the super class is exported
(i.e. Obj-C class is not created at runtime).

Remove incorrect optimization instead of making it more sophisticated,
because it is useless anyway.
