avahi and avahi-autoipd

[Andriy Gapon]

It seems that if net/avahi port is config-ed with WITH_AUTOIPD then
there is a some sort of circular dependency between the two port which
may affect some port management tools. avahi has a run dependency on
avahi-autoipd and the latter has a build dependency on the former.
I am not sure if this is legal from port infrastructure perspective but
it is certainly troublesome for me personally.
