Detection of <resolv.h> in BSD.

[Mats Erik Andersson]

The configuration step of detecting presence of <resolv.h>
is failing on BSD systems like FreeBSD and NetBSD, since
it is a requirement to invoke <netinet/in.h>:

   #include <sys/types.h>
   #include <netinet/in.h>
   #include <resolv.h>

in order to avoid errors.

In addition, BSD systems carry res_query() already in libc,
are thus not in need of libresolv.

The following patch allows build of libshishi on FreeBSD,
NetBSD, and DragonflyBSD.

Best regards,
  Mats Erik Andersson
