Aaaah. I'm silly!

'ares.h' is the main public header file for ares, we can't have that use
#ifdefs that are created by configure, since software including it may not
have those defines!

I did a quick check in the curl headers and I noticed how we have solved it in
curl/multi.h and I decided to use the same in ares.h:

#ifdef _AIX
/* HP-UX systems version 9, 10 and 11 lack sys/select.h and so does oldish
   libc5-based Linux systems. Only include it on system that are known to
   require it! */
#include <sys/select.h>
