RFR: 8370260: Test jdk/jfr/event/oldobject/TestEmergencyDumpAtOOM.java timed out

[Yasumasa Suenaga]

The test failure was reported at jdk/jfr/event/oldobject/TestEmergencyDumpAtOOM.java due to minidump timeout.
`TestEmergencyDumpAtOOM` does not need minidump, so we can add `-XX:-CreateCoredumpOnCrash` to the test process.

This change works on Windows 11 Pro 25H2 and Fedora 42.
