Emily 61922738bb treewide: optimistically unpin FFmpeg 7 dependencies
Per the adjusted FFmpeg pinning advice, packages that work on the
default version should use the unversioned variants to ease the
migration to future versions and reduce the number of packages that
end up referencing old versions.

I have left HandBrake pinned as it builds a custom patched FFmpeg.
