RFR: 8272317: jstatd has dependency on Security Manager which needs to be removed [v4]

[Kevin Walls]

> Remove the use of Security Manager from jstatd.
> Add use of an ObjectInputFilter to restrict RMI.
> 
> Also we can undo the property-setting Launcher.gmk change from: 8279007: jstatd fails to start because SecurityManager is disabled
> ..as that is no longer needed.
> 
> Docs/man page update to follow (JDK-8278619).
