Use a differnt GUID to access the Windows core driver that contains XPS.

The main Windows core printer driver has several different guids associated with it.  Windows 8 removes all but 1 of these guids.
This CL switches to use the guid that is still supported.  AFAICT this should continue to work on all of the platforms we support.
My testing is blocked at the moment due to a problem with internal software.


BUG=139156
TEST=Try to install driver (all supported Windows versions)
