    games/xray_re-tools: unbreak the port's build against Clang 16
    
    Both `std::const_mem_fun1_t' and `std::binary_function' template
    classes had been deprecated in C++11 and removed in C++17, let's
    get rid of them: the latter is just some typedefs and the former
    holds a pointer to a member function and provides `operator()'.
