selftests: ksft: Fix finished() helper exit code on skipped tests

The Python finished() helper currently exits with KSFT_FAIL when there
are only passed and skipped tests. Fix the logic to exit with KSFT_PASS
instead, making it consistent with its C and bash counterparts
(ksft_finished() and ktap_finished() respectively).
