Allow /dev/pts proper permissions so cinder and libvirt work

We need to mount /dev both Libvirt and Cinder containers and
/dev/pts is not correctly mounted.  The /dev/pts recieves no
permissions from the host so it becomes inacessable.
We need to change the permissions of /dev/pts in the container
to 666.
