ve/fs/overlay: allow overlayfs to be used inside a Container
This is temporary decision to make Docker in CT work with overlayfs
storage driver, it can be unsafe to give access to fs-overlay module
from container.
Note: "overlay" kernel module must be pre-loaded on the Host,
it is _not_ autoloaded from inside a Container.

khorenko@: overlayfs stibility in current RHEL7 kernel has not been checked
yet, so it can be used for testing purposes only for now.
