Add Rust for pyca/cryptography 3.4

[mamercad]

See this issue: https://github.com/pyca/cryptography/issues/5771 And the changelog: https://github.com/pyca/cryptography/blob/main/CHANGELOG.rst#34---2021-02-07

Sorry for the "docker stuff" in the commit history, I branched from something else I was doing.

:+1:, the image does not currently build.

A suggestion though: you can add the build dependencies to the apk --update add --virtual line so they will get removed after the python packages get installed.

Ah nice catch, pushed.

The image built for me a few minutes ago (locally).
