cmake: delete duplicate HAVE_GETADDRINFO test 
A custom `HAVE_GETADDRINFO` check came with the initial CMake commit
[1]. A later commit [2] added a standard check for it as well. The
standard check run before the custom one, so CMake ignored the latter.

The custom check was also non-portable, so this patch deletes it in
favor of the standard check.

Closes #9731
