Updated Miscellaneous Journal Traces to lg2

Update the logging API used for files not in
phosphor-fan-presence/presence, phosphor-fan-presence/monitor,
or phosphor-fan-presence/control from the older phosphor::logging::log
to the more recent lg2::log.

Tested:
* Verified journal traces worked correctly in simulation and on
  physical hardware.
* Modified json config files to force parsing and sensor-monitor
  errors and verified correct output and key/value pairs in the
  journalctl output.
