Prevent builds which utilise API deprecated in <= Qt 5.8

Browse Source 
Ideally this would be at least 5.9 (the minimum Qt version supported),
but unfortunately the Qwt libraries utilise QString::null in public
headers which was deprecated in Qt 5.9.

I've got a feeling Qwt is going to be a pain point once again when
Qt6 rolls around...
