Subject: [PATCH] feat(just): add composefs-backend option to disk-image
 (#2370)

This recipe doesn't actually work yet without any changes to the image
because we don't add the bootc module to the initramfs and don't install
systemd-boot.

This makes it easier to test the composefs native backend.
