[Python-Dev] Error in buildbot link

[Eric V. Smith]

http://docs.python.org/devguide/buildbots.html contains a link to
http://python.org/dev/buildbot/, which redirects to
http://buildbot.python.org/index.html, which gives a 404.

I think it should point to http://buildbot.python.org/all/waterfall, or
maybe some subset of it.
