[PATCH] uml: use Kbuild tracking for all files and fix compilation output

Move the build of user-offsets to arch/um/sys-$(SUBARCH), where it's located.
So we can also build it via Kbuild with its dependency tracking rather than by
hand.  While hacking here, fix also a lot of little cosmetic things.
