Add containerenv information to /run/.containerenv

Browse Source 
We have been asked to leak some information into the container
to indicate:
* The name and id of the container
* The version of podman used to launch the container
* The image name and ID the container is based on.
* Whether the container engine is running in rootless mode.

Fixes: https://github.com/containers/podman/issues/6192
