Fixes: NB#257654 - QApplication::applicationDirPath() and QApplication::applicationFilePath() return wrong values for d-boosted applications

Details: Set application attribute Qt::AA_LinuxReinitPathsFromArgv0
         so that QCoreApplication::applicationFilePath() and
         QCoreApplication::applicationDirPath() work correctly
         for d-boosted applications.
