Clean up unused symlink and fixup comment

* These symlinks are no longer used. The other hostnames
  are now configured in operations/puppet.git using proper
  redirects without needing these docroots anymore.

  Deleting them because they mess up primitive tree listings
  such as in Sublime Text 2 (mediawiki sorts before wikimedia,
  and the latter doesn't expand in the tree..)

* Per code conventions, comments go over the lines.
