ksm_tests is a legacy selftest binary and doesn't use kselftest harness/TAP
APIs. It only includes kselftest.h for the KSFT_* exit codes.

This patch is a minimal prerequisite fix. Returning KSFT_SKIP already
provides the correct semantic to the runner, without pulling ksm_tests into the
harness model, which would be a larger refactor.
