server: Reduce PropertiesChanged wakeups

The mapper subscribes to all PropertiesChanged signal events, and
then discards them if the changed interface is not the associations
interface.

Add an arg0 filter on the signal subscription to drastically reduce
the number of spurious wakeups.

Resolves openbmc/openbmc#2573
