[FFmpeg-cvslog] avformat/dvdvideodec: remove auto value for menu_lu option

[Marth64]

ffmpeg | branch: master | Marth64 <marth64 at proxyid.net> | Mon Oct  7 18:05:00 2024 -0500| [60434b483c54aa683a3249a158c8610d5db2fe4a] | committer: Marth64

avformat/dvdvideodec: remove auto value for menu_lu option

The "auto" mode serves no functional purpose except for logging
a message and setting the value to 1. The documentation clearly
explains what the option is for.
