deps/opencv-4/contrib: Fixed and enabled OpenCV4 contrib module
Changelog entry: Fixed and enabled OpenCV4 contrib module
Changes:
- no longer setting opencv_contrib_DIR in OpenCV3 modules but opencv3_contrib_DIR. If needed, then it should be used like this: "OPENCV_EXTRA_MODULES_PATH": "$opencv3_contrib_DIR/modules/aruco" . This allows both opencv3 and 4 to be present at the same time
- fixed and enabled opencv4 contrib
