jammy/binary-amd64 is built on master, but failed on this branch. Do we need to split master_jammy off, or fix the build?

[mmstick]

Requires a newer version of libdav1d than jammy has. It's worth not building for jammy

[jacobgkau]

I've branched master_jammy off of master so this won't affect Jammy.

On Noble, this together with pop-os/cosmic-settings#2051 gets AVIF images showing up in Settings, and they appear as expected when selected.
