kdeobservatory seems to be missing a qwt min version check

[Albert Astals Cid]

Hi guys, can anyone please have a look at
kdeplasma-addons/applets/kdeobservatory and make sure it requires the qwt min 
version it needs?

The build is currently failing at build.kde.org (probably a too old qwt 
installed) instead of just skipping the applet from being built.

Cheers,
