[FFmpeg-cvslog] lavc/dvdec: export bitrate

[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Wed Jun 28 14:17:18 2023 +0200| [9b625ab6792f07fb60b3ce9f2cf5933b2fb0fa1c] | committer: Anton Khirnov

lavc/dvdec: export bitrate

Changes the result of fate-mxf-probe-dv25, where the bitrate is now
exported.

Also changes the result of fate-bsf-dv-error-marker, where the exported
bitrate is now different. Note that the codec layer bitrate does not
match the container bitrate, because container timing is 25fps, while
the DV profile is 50.
