[FFmpeg-cvslog] movenc: encryption with time code track fix

[erankor]

ffmpeg | branch: master | erankor <eran.kornblau at kaltura.com> | Wed May 17 12:32:06 2017 +0300| [15bd309af8302661838150de1905acc4df386d19] | committer: Michael Niedermayer

movenc: encryption with time code track fix

instead of deciding whether to encrypt based on the encryption scheme,
decide according to whether cenc was initialized or not.
mov_create_timecode_track calls ff_mov_write_packet with a track that
doesn't have cenc initialized.
