Module objects compiled from C source can be identified by the presence
of -DKBUILD_MODFILE and -DKBUILD_MODNAME on their compile command lines.
However, module objects from assembler source do not have this defines.

Add $(modfile_flags) to modkern_aflags (similar to modkern_cflahs), and
add $(modname_flags) to a_flags (similar to c_flags).
