auto selet does not select none on a linux without docker

[medyagh]

on a linux box that doesnt have docker
but has podman

medya@podman-exp-temp:~$ minikube start 
😄  minikube v1.9.0 on Debian 10.3
💣  Unable to determine a default driver to use. Try specifying --driver, or see https://minikube.sigs.k8s.io/docs/

medya@podman-exp-temp:~$ docker version
-bash: docker: command not found

we should start either none or podman (experimental) as oppsoed to no running anything

[tstromberg]

none was an intentional decision, and also requires docker.

podman seems reasonable.

I looked at the code, and think it should have fallen-back anyways. Do you mind running --alsologtostderr?
