- Make changes suggested in bsc#1060072

The specific changes are:
  (1) Remove the test in vboxdrv.sh as the script tests for the wrong file. This is safe because
      if the package is not installed, the script will not be there.
  (2) Move VBoxDbg.so to package virtualbox-qt. With this change, packages libQt5Core, libQt5Gui
      and libQt5Widgets are no longer needed with package virtualbox. As a result, a text-only
      server no longer needs to load QT to support headless virtual machines.
