Subject: [PATCH] paraview: add simple validation test

This uses ParaView's `Examples` directory to test an installed ParaView.
Note that these are only really effective as of 5.11.0-RC2 due to
`Examples` having been untested from the top-level prior to this
(ParaView runs its example directories individually itself).
