In Podman 1.9.3,
podman run -p 80
would assign port 80 in the container to a random port on the host. In Podman 2.0 and up, it assigned Port 80 in the container to Port 80 on the host. This is an easy fix, fortunately - just need to remove the bit that assumed host port, if not given, should be set to container port.We also had a test for the bad behavior, so fix it to test for the correct way of doing things.
Fixes #7947
