core: apply LogLevelMax to messages about units
This commit applies the filtering imposed by LogLevelMax on a unit's
processes to messages logged by PID1 about the unit as well.
The target use case for this feature is a service that runs on a timer
many times an hour, where the system administrator decides that writing
a generic success message to the journal every few minutes or seconds
adds no diagnostic value and isn't worth the clutter or disk I/O.

The filtering is applied early in the logging pipeline, before any kind of further processing is done. Moreover, messages which pass through this filter successfully might still be dropped by filters applied at a later stage in the logging subsystem.
