Call VF configuration from udev rules

When a physical function that was allocated to a guest is released back
the system, it is not automatically brought "up" and the VF
configuration is not restored. This patch creates a file containing some
udev rules to force the VF configuration.

Note: we may find that the ifup-local script is no longer required but
this will require further testing.
