host: Don't try to resolve %any* keywords with mismatched address family

Browse Source 
While host_create_from_string_and_family() usually replaces %any*
keywords, this fails if the address family doesn't match (e.g. %any4 with
AF_INET6).  There is no point in trying to resolve these keywords via
DNS as % is no valid character for host names.
