I don't want to write content outside the source and build trees
without explicit local configuration.  A common expectation among
users is that deleting a source and build tree is all that is
needed to wipe out all record of a project having been built.

Furthermore, there is value in de-duplicating dashboard script
code by using vtk_common anyway.
