ci: Enable gfxretrace replay on turnip
To make sure that we keep rendering real apps correctly, we need to:
- build gfxreconstruct in our ARM rootfs in baremetal_build.sh
- Include the gfxr traces in baremetal_build.sh
- Include an X server or wayland server in our ARM rootfs
- Make a new job spawning the server and using tracie-runner-vk.sh
(Or maybe we merge the vk and gl runners?)
