Fix OSX wheel builds

[thisac]

OSX wheel builds are failing. This is an attempt to fix that!

@josh146 The tests now pass (after a bit of tweaking). The only thing is that it's running on Python 3.9, which means that the wheel-uploading might not work on merging with master.

I suspect the following line might cause some errors.

pip3 install --user https://github.com/joerick/libcloud/archive/v1.5.0-s3fix.zip wheelhouse-uploader

I'm not sure exactly why v1.5 is used for libcloud, or if a later version might work as well, although locally, using Python 3.9 under Linux, I can install later versions of both libcloud and wheelhouse-uploader by simply pip install wheelhouse-uploader (in the macOS case, pip3 would need to be used though).

Ah, there is some background here in the cibuildwheel docs:

The reason being that libcloud used to have a bug; however, it might be fixed now?
