Take advantage of XDAMAGE to support Screen Capture under ChromeOS.

Browse Source 
Screen Capture polls under Linux/X11, to avoid issues with poor XDAMAGE
support in some X hardware drivers for things like 3D rendering.

This CL enables XDAMAGE support under ChromeOS, since on that platform we
can make sure that the drivers support it properly.
