src/video/directfb/SDL_DirectFB_render.c: fix build
Build with directfb is broken due to a spurious '}' and a missing 'E'
since version 2.0.12 and https://hg.libsdl.org/SDL/rev/2d5b5a5ccbfb:

/home/buildroot/autobuild/run/instance-2/output-1/build/sdl2-2.0.12/src/video/directfb/SDL_DirectFB_render.c: In function 'SetBlendMode':
/home/buildroot/autobuild/run/instance-2/output-1/build/sdl2-2.0.12/src/video/directfb/SDL_DirectFB_render.c:202:9: error: case label not within a switch statement
  202 |         case SDL_BLENDMODE_MUL:
      |         ^~~~

/home/buildroot/autobuild/run/instance-2/output-1/build/sdl2-2.0.12/src/video/directfb/SDL_DirectFB_render.c:205:67: error: 'DSBF_DSTCOLOR' undeclared (first use in this function); did you mean 'DSBF_DESTCOLOR'?
