[libvirt] [PATCH] Don't mount selinux fs in LXC if selinux is disabled

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

Before trying to mount the selinux filesystem in a container
use is_selinux_enabled() to check if the machine actually
has selinux support (eg not booted with selinux=0)
