FreeBSD port (45): resolv.h syntax error

[Bruno Haible]

When compiling linuxthreads, resolv/resolv.h gives a compilation error when
included with __need_res_state set, because it uses the type 'u_long' but
doesn't always include <sys/types.h>:

In file included from ../include/resolv.h:11,
                 from descr.h:19,
                 from internals.h:29,
                 from condvar.c:23:
../resolv/resolv.h:76: warning: type defaults to `int' in declaration of `u_char'
../resolv/resolv.h:76: parse error before '*' token

	* resolv/resolv.h: Always include <sys/types.h>.
