[PATCH v3 11/16] kunit: Always descend into kunit directory during build

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

An upcoming change will add 'userprogs' to the kunit subdirectory.
For kbuild to properly clean up these build artifacts the subdirectory
needs to be always processed.

Pushing the special logic for hook.o into the kunit Makefile also makes the
logic easier to understand.
