Merge branch '2022-03-02-enable-pylint-in-CI' into next

To quote the author:
This series adds a new errors-only pylint check and adds it to the CI
systems.

It also fixes the current errors in the U-Boot Python code, disabling
errors where it seems necessary.

A small patch to buildman allows it to build sandbox without any changes
to the default config file
