This adds a new env var for identifying the internal sync pipe that libcontainer uses to sync with the container and parent process. This replaces #496 to allow the user to add additional files to the processes and not take over fd 3 for all containers. Closes #496 Signed-off-by: Michael Crosby <crosbymichael@gmail.com>
