When a daemon reaches its timeout when starting, display "timeout" instead

of "ok" so the user is warned and has a chance to fix it (most of the time
due to bogus flags). Daemons reaching the timeout without being able to
start are still marked as "failed" (which should also give a clue to the
user that some investigation is needed).
