cmake/solaris: set CMAKE_REQUIRED_LIBRARIES to fix functions detections

Otherwise we will not detect next functions for instance:
- gethostbyname_r # and related

And now both autotools/cmake builds passes all regress tests in basic env (on
solaris of course).

Fixes: dns/client_fail_requests_getaddrinfo
