[libvirt] [PATCH] udev: should not list bridge devices

[Guannan Ren]

When using udev backend, virsh iface-list outputs bridge devices
like:
 Name                 State      MAC Address
 --------------------------------------------
 em1                  active     e8:39:35:58:d5:94
 lo                   active     00:00:00:00:00:00
 virbr0               active     fe:54:00:a5:f6:42

The patch filters out bridge devices.
