CVE-2013-6456: Avoid unsafe use of /proc/$PID/root in LXC disk hotplug

Rewrite lxcDomainAttachDeviceDiskLive function to use the
virProcessRunInMountNamespace helper. This avoids risk of
a malicious guest replacing /dev with a absolute symlink,
tricking the driver into changing the host OS filesystem.

(cherry picked from commit 4dd3a7d5bc44980135a1b11810ba9aeab42a4a59)
