Michael Niedermayer 49e766aa4c Revert "lavf/mp3dec: don't adjust start time; packets are not adjusted." 
This causes regressions in end to end timestamps with mp3s and ffmpeg.
The revert is to avoid this regression in the 4.3 release

See: [FFmpeg-devel] [PATCH] Don't adjust start time for MP3 files; packets are not adjusted.

This reverts commit 460132c998.
