multiqueue: Use buffer DTS if present, else PTS

Browse source 
In order to accurately determine the amount (in time) of data
travelling in queues, we should use an increasing value.

If buffers are encoded and potentially reordered, we should be
using their DTS (increasing) and not PTS (reordered)
