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.)

Remove suid / gid and execute permission for 'group' and 'others'. 
Similar to: chmod og-ugx /path/to/filename

Removing execution permission is useful to make binaries such as 'su' fail closed rather
than fail open if suid was removed from these.

Do not remove read access since no security benefit and easier to manually undo for users.

chmod 744
