CI: switch to GHA for arm

Since GHA now provides ARM, we can switch away from actuated.

Many thanks to @alexellis (@self-actuated) for being the sponsor of this
project.

PS Currently, criu installed from opensuse build farm repo doesn't work
on GHA arm. While we investigate it, let's disable this combination.
