Log Message:
-----------
Fixed passive option in check_by_ssh
Also:
- On non-skipped stderr, check_by_ssh now returns UNKNOWN or worse (result from command) instead of always UNKNOWN.
- Fixed passive tests and make is always run the specified number of tests (using fail if there's nothing to test).
