Install /usr/lib/qt5/bin/servicefw only from one package.

Currently /usr/lib/qt5/bin/servicefw binary is installed from two different packages: qt5-qtserviceframework and qt5-qtsysteminfo. Each file should be installed only from one package and this will fix and install the file only from qt5-qtserviceframework package.
Good point and I don't have exact answer. But this patch does not change current situation. Currently sfwlisten is installed from qt5-qtsysteminfo package.
