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.
