gst/videomixer/videomixer.c: Use stream_time to synchronize the object properties.

Original commit message from CVS:
* gst/videomixer/videomixer.c: (gst_videomixer_fill_queues),
(gst_videomixer_blend_buffers):
Use stream_time to synchronize the object properties.
Use running_time of the master pad to timestamp outgoing buffers.
Fix the initial segment event to extend an unknown amount of time.
Fixes #537361.
