Revert "matroskamux: Use the running time for container timestamps, not buffer timestamps"

Browse source 
This reverts commit b3aa8755fe.

We are already using the running-time because they were placed on the
buffers with gst_collect_pads_clip_running_time(). Arguably it would be
better to not modify the incomming buffers but collectpads seems to want
to use absolute timestamps from the buffers for finding the best buffer
(this can be changed with a custom compare function..).
