Fix minikube logs for other container runtimes

[afbjorklund]

It is only Docker that adds the "k8s_" prefix, since CRI
only handles containers that are used by Kubernetes anyway.

Also need to use "sudo" when running all crictl commands,
including logs. And only list containers that are running.

Fixes #3744

[afbjorklund]

Wonder why we put the error message in the command to run ? Interesting choice...

I0224 18:31:09.379857    5604 ssh_runner.go:137] Run with output: No container was found matching "k8s_coredns_coredns"
I0224 18:31:09.382572    5604 utils.go:224] ! bash: No: command not found
E0224 18:31:09.383071    5604 logs.go:120] failed: Process exited with status 127

Notice the "No: command not found", as in "No container was found" :-)
