RFR 9 8043477: java/lang/ProcessBuilder/Basic.java failed with: java.lang.AssertionError: Some tests failed

Please review test changes to ProcessBuilder Basic.java to add some 
debugging information.
The test has been failing intermittently.  The wait times have been 
extended to see
if the systems are just slow.  The failure criteria have not changed.

Suggestions welcome.
