Allow MSU-1 SGB games to work properly for the LibRetro core 

This change allows for a SGB boot rom with the same name as a SGB rom to be loaded from the same folder, which allows for MSU-1 enhanced SGB games to work without having to rely on the subsystem menu.
If it fails to load a SGB boot rom from the same folder, it will first revert to the already implemented method of loading the boot rom from the system directory and etc.
