Samba4 config changed so smbd/nmbd don't start anymore
Another change to support Buildroot 2018.05.
The Samba config security option should change from
security = share
security = user
But when you do this it fails to create a file because of a missing directory: /var/lib/samba/private/msg.sock The init script needs to create this directory if it doesn't exist (which it probably won't on each boot) before starting the daemons.
