  GTK+ applications unable to be clicked on in Unity 8

Bug description:
  [Impact]
  GTK+ applications running in Unity 8 do not respond to button presses. This is due to Unity 8 / Mir changing the way events are generated (from mouse events to touch events). The GTK+ backend did not interpret these touch events.

  [Test Case]
  1. Set up a GTK+ application to be launchable from Unity 8 (i.e. edit a .desktop file and set X-Ubuntu-Touch=true)
  2. Log into a Unity 8 session
  3. Click on a button in the application
  Expected result:
  The button is pressed
  Observed result:
  Nothing happens when clicking on the button

  [Regression Potential]
  Low. The fix is just to handle the case of a pointer up/down event where no buttons are specified. This was previously ignored. The GTK+ backend is not usable without making hacks so this is unlikely to affect other GTK+ users.
