build: remove bogus/deprecated inet_* tests

These actually break configure on FreeBSD very subtly, because inet_aton
and __inet_aton are both detected, and then later other tests get
warnings about HAVE_INET_ATON being defined twice.

That said, they're incorrect to begin with since they detect alternative
functions but there is nothing in place to actually use these
alternates.
