kbuild: fix modkern_aflags implementation
For the single target building %.symtypes from %.S, $(a_flags) is
expanded into the _KERNEL flags even if the object is a part of a
module.
$(real-obj-m:.o=.symtypes): modkern_aflags := $(KBUILD_AFLAGS_MODULE) $(AFLAGS_MODULE)
... would fix the issue, but it is not nice to duplicate similar code
for every suffix.
Implement modkern_aflags in the same way as modkern_cflags.
