lib/Kconfig.debug: add list_sort debugging switch
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.
