Submit Subversion directory path in Update.xml

A Subversion revision is unique across the entire repository, but work
trees typically correspond only to a subdirectory below the root path.
In order to specify the version of the source code that was tested,
CTest now submits a <SVNPath> element in Update.xml that specifies the
directory of the repository that corresponds to the work tree.  In
combination with the revision number this uniquely specifies the tested
source.  See issue #7541.
