[libvirt] [PATCH] lxc: Add lxcGetHostname()

[Dan Smith]

This patch adds the getHostname method to the lxc driver structure
(using the qemu driver's generic code).  Apparently virsh started
using that method during console attachment recently.  Without this
implementation, the virsh refused to attach to lxc consoles.
