kproperty translations

[Jonathan Riddell]

There's some fancy stuff in the translations extraction script for kproperty

https://cgit.kde.org/kproperty.git/tree/src/Messages.sh

This breaks the Neon builds which try to parse those Messages.sh files
to download translations

And I'm not sure scripty is happy with it either, there's no
kpropertycore_qt.pot or kpropertywidgets_qt.pot

Is there not an easier way?
