qtdemux: only send initial gaps for non-fragmented streams

It would be unusual to have the header segment with an 'edts' atom
indicating gaps at the beginning when handling fragmented streams.

The header usually doesn't contain any timestamping information, this
should come from the playlist/manifest and the segments with media
in those scenarios.
