QCustomPlot: Fix some warnings in upstream code 

QPainter::HighQualityAntialiasing is obsolete and ignored
(https://doc.qt.io/qt-5/qpainter.html#RenderHint-enum) since
at least 5.6, so use Antialiasing instead, as indicated by the docs.
(https://doc.qt.io/archives/qt-5.6/qpainter.html#RenderHint-enum)
