I agree that this is a better solution however I'm not sufficiently
good in Qt to map all the PyQt modules to their respective
BR2_PACKAGE_QT5xxx variables (for example QtHelp, QtMultimediaWidgets,
...).
That's why I decided to just mess with the dependencies (with the
exception of QtQuick that must be disabled if opengl is not set)

Again, as I'm not a Qt expert, I also missed this one ;-(.
