description:
do not filter address families that are not supported by kernel.
the behavior was introduced in 1.8 -> 1.9, by itojun, and it was
not a correct behavior.

even if we may be able to connect to the the returned addresses,
filtering them out is not a correct thing to do.  for example, even if
you have partial unreachablility in IPv4, gethostbyname(3) will return
IPv4 addresses in the unreachable network nonetheless.
