only use AI_ADDRCONFIG when supported by getaddrinfo

[maxbachmann]

The fallback implementation for getaddrinfo in CPython doesn't support AI_ADDRCONFIG and currently fails with a bad flags error. This changes the implementation to only set the flag if it's part of AI_MASK. Since AI_MASK isn't necessarily available either this has to be checked first.
