BootUp: Clean up elf BootUp code.

Browse Source 
* The file already exsists, otherwise we wouldn't have gotten
   this far in the boot.
 * We have already checked if it's a Wii or GameCube elf,
   besides, it's too late to change our minds now anyway.
 * On Wii - Don't call EmulatedBS2, it can never succeed as
   it knows nothing about booting elfs. Just call the
   SetupWiiMemory directly if needed.
 * On GameCube - We still call EmulatedBS2_GC, but we stop
   it from running Apploader, which might boot something
   unexpected from the default iso or DVD root folder.
