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.
