hrtimer: Update base[CLOCK_BOOTTIME].offset correctly

We calculate the current time of each clock base by adding an offset
to clock_monotonic. The offset for the clock bases is set in
retrigger_next_event() which is called when we switch a cpu to highres
mode or when the clock was set.

Add the missing update for clock boottime.
