Move the "sudo" prefix to a central location, instead of
having it all over the place. Assume only needed on Linux.

Use sudo for the podman commands instead

Wrap the docker commands with env prefix

The `TestOffline/group/crio` integration test was failing with the error:

```
crio load image: sudo podman load -i /var/lib/minikube/images/storage-provisioner_v1.8.1: exit status 125
```

I tried SSH'ing into minikube and running the command myself, and got the error:

```
Error: could not get runtime: please update to v2.0.1 or later: outdated conmon version
```

I then tried updating conmon, but got the error:

```
conmon: error while loading shared libraries: libglib-2.0.so.0: cannot open shared object file: No such file or directory
```

I then tried adding the libglib2.0-0 library to the kic base image and upgrading podman, which seems to have resolved the issue.
