Fix PTS produced by the default OPUS encoder

The default OPUS encoder on Android rewrites the PTS so that it exactly
matches the number of samples.

As a consequence:
 - audio clock drift is not compensated
 - hard silences are ignored

To fix this behavior, recreate the PTS based on the current time (after
encoding) and the packet duration.
