dev-python/pyqtgraph: add qt5 and qt6 USE
net-wireless/gnuradio requires a pyqtgraph that is built against PyQt5 (as previous versions of this package always did). This became apparent when Qt6 was forced to avoid complicated patching of the sources. Revert to editing the sources to enable (and test) only the USE-selected (Py)Qt versions.
