Subject: doc: Remove xhtml validator links.

Fix "privacy-breach-w3c-valid-html" lintian error.

Don't ping an external site when loading documentation
pages since this can be used to track user activity.

These links are also broken, since they depend on the
referer header, which browsers no longer send to insecure
pages for similar privacy reasons. That aspect could be
addressed by using https urls for the validator site.
