  pkcon does not ask debconf questions in Wayland

Bug description:
  [ Impact ]

  `pkcon` is configured to launch the Gtk debconf helper to ask debconf questions graphically.
  This works in Xorg desktop sessions, but does not work in Wayland desktop sessions.

  That is because it starts the Gtk program with a blank environment and
  only adds the DISPLAY environment variable, but not WAYLAND_DISPLAY
  nor XAUTHORITY which would at least have allowed it to display over
  XWayland.

  This is fixed by exposing the WAYLAND_DISPLAY and/or XAUTHORITY
  environment variables to the Gtk program.

  [ Test Case ]

  1. Download `noisy-fake-driver_0.6_amd64.deb` from the attachments.
  2. Run `pkcon install-local ~/Downloads/noisy-fake-driver_0.6_amd64.deb`
  3. Complete the installation
  4. Verify that you saw the "Do you see this message?" question

  [ Where problems could occur ]

  It's fair to assume that the graphical debconf helper hasn't received
  much testing recently, with `apt` defaulting to the text-base helper
  and `pkcon` failing to show it in Wayland; so it's possible that it
  doesn't work well.
