winegstreamer/media_source: Emit absolute presentation timestamp.

Currently the media source emit a presentation timestamp relative to when the playback was last restarted. I.e., the frame that sits two seconds inside a media file will get timestamp 2 if playback was started at the beginning of the file, but will get timestamp 1 if playback was last restarted at second 1. This does not match Windows behavior, where each frame always gets the same timestamp independently from where playback was started.
