tools/lib/list_sort: remove unnecessary header includes

Since lib/list_sort.c no longer requires ARRAY_SIZE() and memset(), the
includes for kernel.h, bug.h, and string.h have been removed.  Similarly,
tools/lib/list_sort.c also does not need to include these headers, so they
have been removed as well.
