bus-util: fix format of NextElapseUSecRealtime= and LastTriggerUSec=

Before this, `systemctl show` for calendar type timer unit outputs
something like below.
```
NextElapseUSecRealtime=48y 3w 3d 15h
NextElapseUSecMonotonic=0
LastTriggerUSec=48y 3w 3d 3h 41min 44.093095s
LastTriggerUSecMonotonic=0
```
As both NextElapseUSecRealtime= and LastTriggerUSec= are not timespan
but timestamp, this makes format these values by `format_timestamp()`.
