Code will never reach SDL_SetTexturePalette since SDL_SetDisplayPalette

Browse source 
will fail if the display e.g. is RGB32 or RGB24. The patch will ignore
errors in SDL_SetDislayPalette.
This should also affect the opengl renderer on systems supporting
paletted textures - mine does not (NVIDIA).
With this patch the directfb drivers delivers the same results for
test_palette like the software renderer.

Kind regards,

André
