Run of external tests - in docker - fails with podman, even with proper podman-docker binding/aliases

[judovana]

What are you trying to do?
I'm trying to run external tests on defualt fedora, install wehre is podman with docker aliases/bindings

Expected behaviour:
exteral tests will work (without removing podman, podman-docker, and withotu replacing it by 3rd party docker)

Observed behaviour:
Currently the podman-docker build faild. I had lost the traces but will elaborate.
It were cryptic messages, suspicions is going to privileged operations. But that is just guessing from air now.

Any other comments:
Possible help from @sefroberg needed

Noting that test-marist-rhel8-s390x-2 probably has our only environment suitable for reproducing this if needed, although it has been commandeered for build work at the moment.
