oggdemux: use the chain begin_time instead of our counter

We update the passed begintime argument to narrow our search region in the
binary search. This means that it does not always contain the chain begin time
after a couple of bisects. Use the real chain->begin_time to bring the
granuletime to the time in the chain instead.

Fixes #610005
