This patch is now in linux-kselftest next. Could you please review
to make sure, it looks right. I had to drop the shared logic from
timers Makefile because, it changed considerably with the additional
tests and it wasn't easy to resolve the conflict and keep both changes.
So at the moment, timers doesn't use the shared logic.

If lib.mk could provide a way to run additional programs that require
arguments in addition to RUN_TESTS. In the case of timers, there is one
test that requires arguments. In some cases, e.g: memory hotplug,
override works well since it is just one executable. In this case,
there is a mix.

Something that can be addressed in a separate patch. For now, I made
the decision to apply with shared logic patch minus the changes to
use lib.mk

thanks,
