kbuild: Really don't clean bounds.h and asm-offsets.h

Commit 7d3cc8b6 tried to keep bounds.h and asm-offsets.h during make
clean by filtering these out of $(clean-files), but they are listed in
$(targets) and $(always) and thus removed automatically. Introduce a new
$(no-clean-files) variable to really skip such files in Makefile.clean.

Kbuild will assume the directories to be in the same relative path as the
Makefile if no absolute path is specified (path does not start with '/').
To exclude certain files from make clean, use the $(no-clean-files) variable.
This is only a special case used in the top level Kbuild file:
no-clean-files := $(bounds-file) $(offsets-file)
Usually kbuild descends down in subdirectories due to "obj-* := dir/",
but in the architecture makefiles where the kbuild infrastructure
is not sufficient this sometimes needs to be explicit.
