Fix memory leak of Reporter through System.err. During the lifetime of a Blaze command, we patch System.out and System.err with custom PrintStream instances (containing a ReporterStream). ReporterStream transitively retains some expensive objects, notably anything registered on the EventBus. Anyone is free to read and retain our PrintStream wrapping ReporterStream via System.out or System.err until the command completes. This change uses an additional layer of control to switch back to the default System.out and System.err and free the custom streams, even if someone retains a reference. RELNOTES: None.
