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.
