Define CLEAN macro to allow Makefiles to override common clean target
in lib.mk. This will help fix the following failures:

warning: overriding recipe for target 'clean'
../lib.mk:55: warning: ignoring old recipe for target 'clean'

Should probably have:

Fixes: 88baa78d1f31 ("selftests: remove duplicated all and clean target")

Amended the change log to add the above.

In hindsight I'm not sure moving the clean target into lib.mk was
the best idea, but anyway it's a bit late to change our mind on that.

Yeah. Moving clean target to lib.mk ended up to be problematic. However,
there are some advantages as well. It will simplify some Makefiles. One
thing that was missed was that not finding the Makefiles that require
overrides. Anyway live and learn.

This patch is a good solution to fix the warnings.
