cam: sdl_sink: Fix compilation with SDL2 <2.0.16

The SDL_UpdateNVTexture() function, used for NV12 texture support, has
been introduced in SDL2 2.0.16. Compiling against older SDL versions
fails with

../src/cam/sdl_texture_yuv.cpp: In member function ‘virtual void SDLTextureNV12::update(const std::vector<libcamera::Span<const unsigned char> >&)’:
../src/cam/sdl_texture_yuv.cpp:19:2: error: ‘SDL_UpdateNVTexture’ was not declared in this scope; did you mean ‘SDL_UpdateYUVTexture’?
   19 |  SDL_UpdateNVTexture(ptr_, &rect_, data[0].data(), pitch_,
      |  ^~~~~~~~~~~~~~~~~~~
      |  SDL_UpdateYUVTexture

Fix it with conditional compilation based on the SDL version.
