rockchip: kodi: add workaround for rendering sw-decoded content on mali4x0 GPUs

Browse Source 
Current upstream mesa has a shortcoming for YUV12 to XR24 conversion
so that DRMPRIMEGLES conversion cannot be used (for details see
https://gitlab.freedesktop.org/mesa/mesa/-/issues/4074)

This adds a patch to kodi to not use this on lima GPUs and allow
proper fallback to LinuxRendererGLES where shaders are used and the
conversion is working.
