#5231: Unncessary forward declaration of std::pair

------------------------------+---------------------------------------------
 fusion/adapted/std_pair.hpp contains a forward declaration of std::pair.
 This upsets libc++.

 However, <utility> is also (I believe) always included anywhere (at least,
 in every test I did), so the forward declaration isn't very useful anyway.
 This patch just replaces it with a #include <utility>. For me, this very
 slightly decreases the size of the pre-processed file on both mac and
 linux g++.
