ProcessTools executeTestJvm and createJavaProcessBuilder have inconsistent handling of test.*.opts

1) executeTestJvm(cmd) adds test.vm.opts and test.java.opts
2) createJavaProcessBuilder(cmd) does *not* add test.vm.opts or test.java.opts
3) createJavaProcessBuilder(true, cmd) adds test.vm.opts and test.java.opts.

I think we should change so that (1) and (2) are consistent in the behavior.
