upstream ci: Remove dependency on molecule

We only use molecule to build images and start testing containers, which
adds unneeded complexity by increasing the software stack in a way that
does not bring any advantage.

There's also risk that changes on molecule break the tests, which has
happened a few times.

This change removes the dependency on molecule by using docker/podman
directly to build and run the test containers.
