mdmon: don't lie to systemd.

Now that mdmon responds fairly well to SIGTERM, stop lying to
systemd about being started on the initrd.

Note that if mdmon is rerun (--takeover) for some reason, and systemd
chooses to kill processes before remounting / readonly, then the
unmount will hang.

If systemd ever lets us tell it that we don't want to be killed until
root is readonly, then we should do that.
