ram wipe on shutdown: fix, added need_shutdown hook
...
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.

...
- Confirm in console output if encrypted mounts (root disk) is unmounted. (Because that is a pre-condition for wiping the LUKS full disk encryption key from RAM.)
