Fix seeking near the start of saved live streams. If a stream starts with a non-zero granpos, we would subtract 80 ms from the target time, and then report failure when the best page we could find (the first page in the link) had a granpos larger than that. This worked for normal streams because the subtraction would fail (granpos can't wrap past -1) and we checked for that.
