chore: rename joerick/cibuildwheel -> pypa/cibuildwheel (#682)

* chore: rename joerick/cibuildwheel -> pypa/cibuildwheel

* Update Appveyor status badge markup

Note that it still has joerick/cibuildwheel - confusingly it's still within my appveyor account, but this is the new project that points to the pypa github repo

* Update Appveyor badge markup again

I went through a few passes to enable that project, here's the latest.

* Update Azure badge, also

* Update Travis badge to reference the .com
