movenc: Indicate that negative timestamps are supported
The mov/mp4 muxer has support for handling negative timestamps via edit lists (which customarily is used for handling the 1-frame delay due to B-frames as well). Using the muxer's native way of handling it is better than using the generic offsetting. The generic offsetting is a bit too crude when e.g. the timebase of one track is 1/fps, where the edit lists can handle it accurately. Signed-off-by: Martin Storsjö <martin@martin.st>
