qtdemux: accumulate previous edts entries into segment.base

Browse Source 
Allows playing edts editted files with proper synchronization of
streams. This patch fixes the regression introduced by
bf95f93c0189aa04f18e264b86b6527e431c5d53 that was added to fix
segment seeks handling.

Having the accumulated_base separated from the main segment.base
allows handling both segment seeks and edts editted files.
