fix printf compiler warnings due to Box2D_typemaps.i

when compling pybox2d in Mac OS X 10.9 with clang, I get many, many warnings 
like

Box2D/Box2D_wrap.cpp:19157:92: warning: format specifies type 'int' but the
      argument has type 'Py_ssize_t' (aka 'long') [-Wformat]
  ...or list of length 2, got length %d", PySequence_Size(swig_obj[1]));
                                     ~~   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
                                     %ld

It looks like on gcc it's even worse because, I guess of in-lining, the error 
gets emitted from any function that accepts a b2Vec2.

I think the patch included, applied to /Box2D/Box2D_typemaps.i, should remove 
the warnings. The cast to (long) is because Py_ssize_t is "int", I think, on 
32-bit platforms.
