basesrc: Only set DTS to segment.start on the first buffer if subclass did not provide PTS

Browse source 
Otherwise we're going to set a rather arbitrary DTS of segment.start (usually
0) for live sources, which confuses synchronization if the source started
capturing at a later time. And it's especially wrong for raw media, for which
we should not set any DTS at all.
