[Python-buildbots] Buildslave cleanup

[Zachary Ware]

I've just gone through and removed buildslaves that have been offline
for a long time.  The only currently-offline buildslaves remaining are
bruynooghe-solaris-csw and cea-indiana-amd64.  Floris and Jesús, could
you give me an update on the status of your slaves, please?

I'm planning to reshuffle the stable and unstable sets in the next
week or two, and would like to have all-online slaves at that point :)

Thanks,
