wipe RAM at shutdown: Ensure any remaining disk cache is erased by Linux' memory poisoning 
by running:
`echo 3 > /proc/sys/vm/drop_caches`

Inspired by Tails:

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.
