Did you validate that we no longer need --cap-add=MKNOD?

We definitely need --privileged when doing cross-builds in order to set
up binfmt if the host is not using it.

Here is a working reference for native as well as cross-setup:

https://github.com/siemens/jailhouse-images/blob/master/build-images.sh

It also demonstrates how to avoid that interactive mode (which is what
you normally want when you aren't developing on details). Plus, it
addresses the proxy topic.
