Allow to run wopi example deployment with podman

podman doesn't have a "local" log driver. Also it's docker-compatibility
socket does live in a different location (especially when running
rootless podman).

With this change you can run the deployement with a recent podman
version using:

LOG_DRIVER=journald DOCKER_SOCKET_PATH=/run/user/1000/podman/podman.sock podman compose start
