ltp-guf-tests: Dual screen: add bball and fingerpaint to run on 2 screens.
With the kioskshell two instances of the same tool are needed with different app-ids/names. This creates a new bball test, as QT binary ( the previous one just started qmlscene) and a hardlink to fingerpaint2. With a adapted weston.ini these can be shown each on its own screen.
