[PATCH][wily] UBUNTU: SAUCE: overlayfs: Enable user namespace mounts for the "overlay" fstype

[Seth Forshee]

User namespace mounts were mistakenly only enabled for the
"overlayfs" fstype and not for the "overlay" fstype. This is a
regression in behavior towards userspace from previous Ubuntu
kernels and breaks some features of LXC.
