Gtk: disabled ^Z suspension on Unix for the time being

* This has always been broken as Gtk will not hide the
  window before suspending.
* It has been deemed to complicated to implement at the moment.
  Even if we can catch SIGTSTP (not that trivial), it seems to be
  impossible - at least without some lower level Xlib interaction -
  to hide the program window before raising SIGTSTP.
* Even if everything worked, it is unclear whether it is actually
  desirable to suspend a GUI application - ^Z may be pressed accidentally
  and it will be inconvenient to resume the job.
  So we would additionally have to check for the existence of
  an attached console.
