lorri: don't start until daemon is really running

Sometimes a race condition will make the events stream start after the
daemon is running, and then no events will be streamed.

This fixes the problem by checking the daemon status and failing the
unit if not ready yet. It will restart 5 seconds later, which will
probably be enough.
