libhb: fix incorrect audio gaps

When the duratation of an audio packet is not evenly divisible by the
90khz clock, we were loosing a fraction of a tick per audio packet.  This
causes every packet to be tagged with a timestamp that is a little early
and eventually a gap must be filled to maintain sync.
