8325203: System.exit(0) kills the launched 3rd party application

[alexeysemenyukoracle]

Tested with the use case from the CR.

The idea of the fix is to prevent grandchildren processes from being automatically attached to the job killing all processes attached to it when the job object is destroyed.

Filed a follow-up https://bugs.openjdk.org/browse/JDK-8325525 CR to track adding a jtreg test for the issue.
