modemmanager: refactoring hotplug debug logging

The output of the hotplug is very chatty and floods the log with
messages that are not necessary in functioning operation.

So that the log can be filtered. A log level was added to each message
as the first opiton on mm_log function call.

In addition, the facility of the hotplug script has been set to daemon,
which in my view fits better than user.
