[libvirt] [PATCH v2 3/4] interface_backend_udev: Implement link speed & state

[Michal Privoznik]

In the previous commit the helper function was prepared, so now
we can wire it up and benefit from it. The Makefile change is
required because we're including virnedev,h which includes
virnetlink.h which tries to include netlink/msg.h. However this
file is not under /usr/include directly but is dependent on libnl
used.
