Stop publishing local absolute paths from the viz tools README

viz_tools/README.md linked the tools via file:///Users/... absolute
paths, which are broken for anyone cloning the repo and became publicly
visible once docs/tools symlinked the folder into the site. Make the
links relative, and exclude the README from the docs build so the
folder contributes only the two HTML apps.
