[dbusconfiguration] Allow partial configurations

In a few cases (cpu sensors, etc.) we can
add sensor during runtime, that aren't an error to be missing
when the system is off, or are optional (add-in cards).
Add a dbus match to restart on sensors added, and don't
add configurations that are missing a sensor.

Tested-by: Turned on debug, noticed on cpu sensors being
added daemon restarted correctly. Also noticed daemon
didn't crash with no configuration.
