stdinc: excplicitly cast output of __builtin_bswap32 to Uint32

Browse source 
This fixes a compile warning when using the output of SDL_Swap32
directly using the SDL_PRIu32 macro in C90 mode:
testplatform.c:158:17: warning: format '%lX' expects argument of
type 'long unsigned int', but argument 3 has type 'unsigned int' [-Wformat=]
  158 |         SDL_Log("Value 32 = 0x%" SDL_PRIX32 ", swapped = 0x%" SDL_PRIX32,
