haiku: Fix when screen color depth was 24 bits, SDL_GetWindowSurface would always fail with 'Unknown pixel format' error 

Note that returning SDL_PIXELFORMAT_BGR24 instead of SDL_PIXELFORMAT_RGB24 seems necessary, otherwise when running with SDL_ACCELERATION=0, the red and blue channels of the window appeared swapped.
Note that when running with acceleration enabled, red and blue channel swapping does not happen regardless of whether SDL_PIXEL_FORMAT_RGB24 or SDL_PIXEL_FORMAT_BGR24 is returned.

For good measure, I also tested running with acceleration disabled in both 15 and 16 bit color depths, but red and blue channel swapping did not occur
