Modify greedy pete for kill 9 signals

When greedy pete is running and reaches the max memory allocation it
receives a kill 9 signal which doesn't allow it to write the difference
between start and end diagnostics.

Also added log option for no logs since get_diganostics call logs
every call which we are calling for every memory increment.

Also modified Jamroot compilation to not treat deprecated declaration
warnings as errors. I kept getting "error: ‘auto_ptr’ is deprecated"
which I'm not using within these tests.  Was not able to figure why I
kept getting these errors.
