Replace std::make_tuple with simpler syntax (#77) * boot2: Simplify g_additional_launch_programs It appears that Stratosphère is targeting C++17. In C++17, std::make_tuple is not required for initialisating a tuple anymore. Same thing, but less typing * Replace std::make_tuple with {} More readable and less noise. Also fixes two missing return statements.
