ci/lava: Use the new test-video-based rootfs for VA-API jobs

Add new job definitions using the new debian/x86_64-test-video container,
and convert the radeonsi-raven-va and radeonsi-raven-vaapi-fluster jobs
to use the rootfs derived from this container.
Now that we are no longer downloading the Fluster vectors at runtime, the
parallelsim of the radeonsi-raven-vaapi-fluster job can be greatly
decreased.
