libreplace: undef AI_ADDRCONFIG on QNX 6.3.0 (fix bug #6630)

Some of the functions in source3/lib/util_sock.c use AI_ADDRCONFIG.  On QNX
6.3.0, this macro is defined but, if it's used, getaddrinfo will fail.  This
prevents smbd from opening any sockets.

If I undefine AI_ADDRCONFIG on such systems and allow
lib/replace/system/network.h to define it to be 0, this works around the issue.
