[FFmpeg-cvslog] lavf/movenc: fix tmcd writing for non-MP4/MOV modes

[Gyan Doshi]

ffmpeg | branch: master | Gyan Doshi <ffmpeg at gyani.pro> | Sun Mar 31 00:18:50 2019 +0530| [8161ac2902836032b6f6684aa48275325f8ca9ef] | committer: Gyan Doshi

lavf/movenc: fix tmcd writing for non-MP4/MOV modes

write_tmcd allows tmcd track to be created with any mode but in
mov_write_header, index for first tmcd track is only set for modes
MP4 or MOV, causing a crash if tmcd creation is attempted with other
modes.
