This PR resolves building on Ubuntu 20.04 [which is our default](https://github.com/apache/arrow/blob/master/.env#L45) though the crossbow build in tasks is [on 20.10](https://github.com/apache/arrow/blob/master/dev/tasks/tasks.yml#L949) which has one of these additions, but also a newer protobuff so that's not needed to be bundled. We also might consider _not_ adding these lines but making clear in the docker compose file that `ubuntu-docs` will not work with Ubuntu 20.04 and instead should always be build on 20.10 -- This is an automated message from the Apache Git Service.
