Bug#843897: Should allow pyqt5

[Yuri D'Elia]

Package: python-pyqtgraph
Version: 0.9.10-5
Severity: normal

pyqtgraph 0.10 can now also work with pyqt5. I'd suggest adjusting the
dependencies to allow this.

python-pyqtgraph should depend on python-qt4 | python-pyqt5 | python-pyside
python3-pyqtgraph should depend on python3-pyqt4 | python3-pyqt5 | python3-pyside

Thanks.
