package/opencv: fix webp dependency

Browse Source 
When BR2_PACKAGE_OPENCV4_WITH_WEBP=y we need to enable mux and demux
support in webp, otherwise the build of OpenCV fails as follows:

    CMake Error: The following variables are used in this project,
         but they are set to NOTFOUND.
    Please set them or make sure they are set and tested correctly
         in the CMake files:
    WEBP_DEMUX_LIBRARY
    linked by target "opencv_imgcodecs"
         in directory [...]/build/opencv4-4.13.0/modules/imgcodecs
    WEBP_MUX_LIBRARY
    linked by target "opencv_imgcodecs"
         in directory [...]/build/opencv4-4.13.0/modules/imgcodecs

The issue already exists in 2025.02.x.
