getaddrinfo test: ignore failure on AIX

[Bruno Haible]

The getaddrinfo test also fails on AIX 4 and 5:

Finding www.ibm.com service https...
res 7: Host not found

7 is EAI_NODATA, meaning "no address associated with hostname". But
when ("www.ibm.com", "https") fails with this error whereas
("www.ibm.com", "http") succeeds, it's clear that the error is buggy.

I apply this, since it's now a known failure:
