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

Rewrite lxcDomainAttachDeviceHostdevStorageLive 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.
