tools/systemd/time: fix compute_next_event for weekdays

two things were wrong here:
* the range (x..y) does not include y, so the range
  (day_num+1..6) goes from (day_num+1) to 5 (but sunday is 6)

* WeekDays.bits() does not return the 'day_num' of that day, but
  the bit value (e.g. 64 for SUNDAY) but was treated as the index of
  the day of the week
  to fix this, we drop the map to WeekDays and use the 'indices'
  directly

this patch makes the test work again
