[libvirt] [PATCH 1/3] Ensure LXC security driver is set unconditonally

[Daniel P. Berrange]

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

The driver->securityDriverName field may be NULL, if automatic
probing is used to determine security driver. This meant that
unless selinux was explicitly requested in lxc.conf, it was
not being sent to the libvirt_lxc process.

The driver->securityManager field is guaranteed non-NULL, since
there will always be the 'none' security driver present if
nothing else exists. So use that to set the driver name for
libvirt_lxc
