sensor-mon: Check service on D-Bus at power on

If sensor-monitor has detected a threshold alarm when power is off, it
would log an error for that when the power turns on.

Add a check that the alarm interface is still on D-Bus before logging
the error, in case the sensor-daemon stopped running.

Alternatively, the code could listen for a NameOwnerChanged signal to
see if the daemon stopped, but then it would have to keep a map of
sensor names to service names and always keep it up to date.  The chosen
method seems more straightforward and less error prone.
