On AIX, there is a possibility that the child process is done before the parent debugger can connect to it. So prolong the child process by factor of 2.

Fixes: #14897

Still looking a bit flaky: 1237 OK: 1228 NOT OK: 9 TOTAL: 9999

Is there a way for the child process to pause until the debugger is attached?

Maybe replace --inspect=0 with --inspect-brk=0 (there's already a Runtime.runIfWaitingForDebugger that will "continue" execution)

LGTM the change but I think we also need to revert the AIX part of 7027191 so that it is no longer marked as flaky for AIX.

I think earlier stress test showed it was good.

New CI since it has been 2 weeks: https://ci.nodejs.org/job/node-test-pull-request/11152/
