 Summary of the bug:
 End trimming test cases for opus-in-mp4 using edit lists don't work
 properly. Converting either of the attached mp4 files to wave and playing
 back the result will correctly trim the pre-skip at the front, but doesn't
 remove the beep at the end.

 AFAICT the edit list isn't being utilized correctly for these files.

 How to reproduce:
 {{{
 % ffmpeg -i opus_fragmented.mp4 out.wav
 % ffplay out.wav

 ffplay version N-101553-g434b626b7a Copyright (c) 2003-2021 the FFmpeg
 developers
   built with gcc 9.3-win32 (GCC) 20200320
