ci/lava: Remove vkd3d-proton from the core rootfs

Remove the /vkd3d-proton directories from the core LAVA rootfs archive
and upload vkd3d-proton as a separate archive for use as an optional LAVA
overlay.

This reduces the size of the core lava-rootfs tarball and ensures
vkd3d-proton is only deployed when the job needs it.
