Subject: dracut: Disable ostree-prepare-root


Resolves: RHEL-35885

    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:
    https://github.com/ostreedev/ostree/pull/3220/commits/05b3b662756def30026fc722d0832a24a33d9803

    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.
