veyron/security/agent/agentd: kill child command when the agent is killed

If the agent receives a signal like TERM or INT, we want the agent to first kill
its child before exiting.  The change makes agent listen for ShutdownOnSignals
and relay the received signal to the child (so that the child has a chance to
shut down cleanly).
