qtdemux: simplify segment.base math

Browse source 
Remove a fix for heavily edited files added for fixing
https://bugzilla.gnome.org/show_bug.cgi?id=345830 to work
with seeks and proper gaps playback. The fix was replaced
for a more general solution that bases on using previous
segment's duration, just like it works for media segments
playback.
