FreeBSD's vfs_mountroot() will collect `mnt_time` from every filesystem that we mounted and use the highest timestamp as a source for the system time if we didn't get anything from an attached RTC. Use the rrd mechanism added to gather up a notion of the latest time and set it on mnt_time. If the timestamp db is empty, we just fallback to the uberblock timestamp and hope that that is in the right ballpark.
