If we are running in a user namespace, don't try to mknod as
it won't be allowed. libcontainer will bind-mount the host's
devices over files in the container anyway, so it's not needed.
The chrootarchive package does a chroot (without mounting /proc) before
its work, so we cannot check /proc/self/uid_map when we need to. So
compute it in advance and pass it along with the tar options.

That function is pretty heavy used on container start. Autoallocating
buffer can be painful.

This only renames docker internal structures.
It has no impact on the end-user.
