Move the network setup back into the standard init even for user
namespaces now that mounts are fully supported and working.

This updates the console handling to chown the console on creation to
the root user within the container.
This also moves the setup mounts from the userns sidecar process into
the main init processes by trying to mknod devices, if it fails on an
EPERM then bind mount the device from the host into the container for
use. This prevents access issues when the sidecar process mknods the
device for the usernamespace returning an EPERM when writting to
dev/null.
This also adds some error handling for init processes and nsinit updates
with added flags for testing and other functions.
