Subject: Detect if in podman machine virtual vm

When in podman machine virtual machines, podman needs to be able to
detect as such.  One implementation for this is when creating networks,
the podman-machine cni plugin needs to be added to the configuration.

This PR also includes the latest containers-common.

[NO TESTS NEEDED]
