Revert "player: add track-list/N/image sub-property"
Unfortunately, this functionality in large part based on a struct
member that was made private in FFmpeg/FFmpeg@7489f632815c98ad58c3db71d1a5239b5dae266c
in May. Unfortunately, this was not noticed during review.
This reverts commit 0862664ac952d21fef531a8923a58ae575268fc5.
