avoid suicide

container.Kill() might read a pid of 0 from
container.State.Pid due to losing a race with
container.monitor() calling
container.State.SetStopped(). Sending a SIGKILL to
pid 0 is undesirable as "If pid equals 0, then sig
is sent to every process in the process group of
the calling process."

Add exported status code from a job

This allows the job's status code to be consumed externally so that we
can use it as an exit code or saving to a state file.
