lib/Kconfig.debug: add list_sort debugging switch

Browse Source 
While hunting a non-existing bug in 'list_sort()', I've improved the
'list_sort_test()' function which tests the 'list_sort()' library call.
Although at the end I found a bug in my code, but not in 'list_sort()', I
think my clean-ups and improvements are worth merging because they make
the test function better.

This patch:

Make the self-tests selectable via Kconfig rather than by manual enabling
of DEBUG_LIST_SORT.

Enable this to turn on 'list_sort()' function test. This test is
executed only once during system boot, so affects only boot time.
