package/opencv4: BR2_PACKAGE_OPENCV4_LIB_OBJDETECT requires BR2_PACKAGE_OPENCV4_LIB_DNN
Opencv4 library objdetect needs library dnn, otherwise it throws:
```
-- Module opencv_objdetect disabled because opencv_dnn dependency can't be resolved!
```
So let's "select BR2_PACKAGE_OPENCV4_LIB_DNN" if
BR2_PACKAGE_OPENCV4_LIB_OBJDETECT is enabled.
