Use `retry` command on circleci build tools uploads

We hit what looks to be an intermittent failure to download a Python tarball:

Downloading python-build...

We can maybe protect against this with the retry command:

Or even just a basic bash hack of this to retry 3 times.

I may need to take a look at this since I'm hitting random issues while compiling the build tools today.
