Make Chrome's clipboard compatible with mono apps

Make Chrome's clipboard compatible with the clipboard for mono apps (http://www.mono-project.com/)

A request for the "TARGETS" target of the clipboard selection via
XConvertSelection(display, selection, target, property, requestor, time)
should set |property| to a property of type XA_ATOM. Mono apps set |property| to a property of type "TARGETS" instead.

This CL treats a property of type "TARGETS" the same as a property of type XA_ATOM.

BUG=377893
TEST=Manual, see bug

dcheng@ can you please take a look?

I have filed a bug against mono at
https://bugzilla.xamarin.com/show_bug.cgi?id=20326

The main reason I am putting this CL up for review is in case some other library
has the same bug. This is a very easy bug to make and the spec is not that easy
to read.
