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

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