systemctl: add --timestamp to change timestamp print format

Timestamps for unit start/stop are recorded with microsecond granularity,
but status and show truncate to second granularity by default.
Add a --timestamp=pretty|us|utc option to allow including the microseconds
or to use the UTC TZ to all timestamps printed by systemctl.
