ctest_update: Add CTEST_UPDATE_VERSION_ONLY option to only note the version

This allows ctest_update to get the current version without actually
changing the repository.  This is useful when using Jenkins or an
external project to update the source to a specific version, but you
still want the current version to show up in CDash.
