GH Actions: Repair upload of docker images to docker.pkg.github.com

[mkoeppe]

These docker images are built by the portability CI workflows for Linux.

However, refactoring of the workflow had broken the upload to docker.pkg.github.com. (Although the login to docker.pkg.github.com succeeds, the push fails with no basic auth credentials - see https://github.com/mkoeppe/sage/runs/1414148202?check_suite_focus=true)

This is possibly because tox does not pass on $HOME - and docker login stores the password in /home/runner/.docker/config.json.

docker login recommends to configure a credential helper -
