requirements: Add dependencies for two-factor auth.

We're not yet ready to add 2FA to Zulip yet, but we've determined we'd
like to work from these libraries.

I'm not bothering to bump PROVISION_VERSION for this, since we're
likely to do something else that bumps it soon, and we're not merging
anything that uses these new libraries.
