allow getaddrinfo flag AI_ADDRCONFIG to be disabled
This flags is generally handy to avoid having to deal with ipv6 results on an
ipv4-only system, but it prevents e.g. the testcases from working if the
testsystem has no configured address at the moment (expect loopback), so
allow it to be sidestepped and let the testcases sidestep it.
