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.
