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.

- Wipe LUKS Disk Encryption Key for Root Disk from RAM during Shutdown to defeat Cold Boot Attacks 
- 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.)

Thanks to @friedy10!
