[wayland] Force Qt::AA_NoHighDpiScaling on Qt 5.6

Browse source 
We already unset QT_DEVICE_PIXEL_RATIO to ensure to keep out of
high dpi scaling. Now with Qt 5.6 we also need to set the attribute.
Without we crash on startup as we don't have a screen that early and
well Qt doesn't check whether it's null.
