After creating a filesystem using newfs -j the time stamps are all

zero and thus report as having been made in January 1970. Apart
from looking a bit silly, it also triggers alarms from scripts
that detect weird time stamps. This update sets all 4 (or 3, in
the case of UFS1) time stamps to the current time when enabling
journaling during newfs or later when enabling it with tunefs.
