regression: gif(4) configuration broken since 10.x

[Eugene Grosbein]

Hi!

Upgrade from earlier versions to 10.x оr 11 breaks gif(4) tunnels
no matter if they are described using cloned_interfaces or gif_interfaces
rc.conf configuration directives: interfaces get created and tunnel addresses
assigned but miss configured inet addresses.

There is trivial patch and PR over a year but problem is still here:

Please fix it.
