runsc: Pass root container's stdio via FD.
We were previously using the sandbox process's stdio as the root container's
stdio. This makes it difficult/impossible to distinguish output application
output from sandbox output, such as panics, which are always written to stderr.
Also close the console socket when we are done with it.
