ram wipe on shutdown: fix, added need_shutdown hook

Browse source 
Otherwise dracut does not run on shutdown.

Without `need_shutdown` file `/run/initramfs/.need_shutdown` does not get created.
And without that file `/usr/lib/dracut/dracut-initramfs-restore`,
which itself is started by `/lib/systemd/system/dracut-shutdown.service` does nothing.
