EMI: Directly use converted buffer

Browse Source 
Data is already converted to the correct format by copyBuffer, so write
it directly to save file.
This fixes save game screenshots taken with TinyGL renderer: Bitmap
constructor calls graphic driver's createBitmap method, and TinyGL's
converts the buffer to its own buffer pixel format - undoing the conversion
storeSaveGameImage did just before.
