Based on the description in commit 63ef557 this was added so that the
migrate command does not move the pause process into a separate cgroup.
It should however not disable the rejoining of the userns when the pause
process join failed. BEcause of this we end up calling migrate without a
userns and that then can fail if there are actual contianer it tries to
cleanup.
