mp4mux: Fix edit list shift for streams with initial DTS smaller earliest PTS but initial DTS positive
This would be a stream where the initial DTS is negative if the initial
PTS was zero, but it is offset so the initial DTS became positive now.
The edit list shift has to happen exactly the same way though.
