ffmpeg-nvenc-jammy.patch

FFmpeg n7.1 will accept NVEnc 11.5.1.3+, but not Ubuntu 22.04's packaged
version, 11.5.1.1.  This patch makes it flexible enough to build with the older
NVEnc version in Ubuntu Jammy.  For code archaeologists, the commits that set
the minimum beyond 11.5.1.1 were
https://github.com/ffmpeg/ffmpeg/commit/5c288a44 (released in n6.0) and
https://github.com/ffmpeg/ffmpeg/commit/05f8b2ca (released in n6.1).
