[PATCH RFC] kbuild: fixes in Makefile.lib

From: Cao jin

commit

cf4f21938e13e ("kbuild: Allow to specify composite modules with modname-m")

add modname-m support, but miss to update the corresponding multi-objs-m
defination.

commit 551559e13af1c ("kbuild: implement modules.order") miss to filter
the subdir listed in obj-m. Except that the subdirs are totally identical
between obj-y and obj-m, or else I think it will miss something.

But until now, no one has complaining about it, so I guess it just no
one has triggerred it.

I found these 2 points which I think might be wrong during code
inspection, but until now, they seems didn't do anything bad, so I am not
sure this is a problem:)
