dracut: Disable ostree-prepare-root

In some images such as the recent fedora/rhel bootc base image, the ostree dracut module is statically enabled: https://gitlab.com/fedora/bootc/base-images/-/blob/40df0eb3827763039e4d17264968e37f850b70e5/tier-0/initramfs.yaml#L9 And also recently, we changed the ostree systemd unit to enter emergency.target if it fails in: ostreedev/ostree@05b3b66 These two things combine mean we'll fail before kdump gets a chance to run. For our use case we don't need ostree in the initrd. I tried to override this with `--omit=ostree` in our dracut invocation, but that causes an error (dracut doesn't let the cmdline override static config). For now, let's just mask the service in our initrd. Signed-off-by: Colin Walters <[email protected]> Reviewed-by: Lichen Liu <[email protected]>
