wireshark: add CLI and Qt versions

In addition to our existing GTK version.

* Only install desktop file if building a GUI version.
* The Qt build appends "-qt" to the
  wireshark binary name. Undo it so the desktop file works.
* The 'wireshark' attribute still refers to the GTK version, for
  backwards compatibility.
