[FFmpeg-cvslog] avformat/segafilm - revert keyframe detection

[Gyan Doshi]

ffmpeg | branch: master | Gyan Doshi <ffmpeg at gyani.pro> | Sat Apr 21 13:02:12 2018 +0530| [9f9f56e6791f6c44ac8e4b97a8da5816ed542332] | committer: James Almer

avformat/segafilm - revert keyframe detection

Keyframe detection was inverted in cfe1a9d311 in order to fix keyframe
flags set for the sample attached to trac #7091. However, that sample is
errantly muxed.

As noted at
https://web.archive.org/web/20020803104640/http://www.pcisys.net:80/~melanson/codecs/film-format.txt,
the original keyframe detection logic is correct, and this patch
restores it.
