System info does not consider other container runtimes

[ykgmfq]

The problem

Deployment of the official HA container on container runtimes which do not provide /.dockerenv results in installation type "Unknown". The expected type is "Home Assistant Container".

One such container runtime, Podman, provides the environment variable container=podman instead of the file /.dockerenv, see containers/podman#529.

In system_info.py, I propose to set info_object["docker"] to true when either /.dockerenv is present or os.environ.get('container') is true.
