Subject: [PATCH] System: Make sure to exit the loop on receiving SDL_QUIT

This is fixed in more modern adaptations, as can be seen here:

https://github.com/laanwj/gltron/blob/336dbbb75afe0aed1d9faaa5bbaa867b2b13d10b/nebu/base/system.c#L135

Since we work with the original source material, we better patch this
ourselves.
