Update console and mount handling for user namespaces
...
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.

When running under child subreaper mode, it's useful for nsenter to be able to
