Fix crash happening on 8 and 16 bit color displays. 

Commit f51dbd0669 changed the way of generating
images of ships taking damage, and assumed that the SDL_Surfaces containing the
images were always 24 or 32 bpp. However, SDL will already have converted them
to the display format, so we need to properly handle 8 and 16 bpp as well.
