Tools:

The test is failing because the clickPoint values remain unchanged. The
values remain unchanged because ATK lacks a means to keep track of this
information.

* DumpRenderTree/gtk/AccessibilityUIElementGtk.cpp:
(AccessibilityUIElement::clickPointX): Added comment that ATK doesn't have clickPoint details
(AccessibilityUIElement::clickPointY): Added comment that ATK doesn't have clickPoint details

LayoutTests:

This test seems to be Mac-specific. Therefore, move the test to that
platform and remove the skips from the other platforms.
