[libvirt] [PATCH] Handle ENOTSUP from setfilecon on FUSE in LXC startup

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The setfilecon method can return ENOTSUP when trying to set the context of the /proc/meminfo FUSE filesystem. We must ignore this error and carry on, to prevent container startup failing entirely Signed-off-by: Daniel P.
