Submit global tree revision in Update.xml

We teach CTest to report in a <Revision> element the revision of the
source tree that was tested.  This makes sense for all modern VCS tools
because they version the whole tree.  We simply omit this element for
CVS because it only versions files.  See issue #7541.
