Revert 'ExitOnOutOfMemoryError' setting because it requires minimum Java 8u92

[jordansissel]

our support matrix targets Java 8u60, but 'ExitOnOutOfMemoryError' was only added in Java 8u92.

We need to revert ExitOnOutOfMemoryError as long as we don't require 8u92 or higher.

[jordansissel]

Elasticsearch has a custom thread exception handler that basically implements exit-on-oom without the need of the 8u92 ExitOnOutOfMemoryError flag (and does a bit more, it terminates on any Error) elastic/elasticsearch#19272

Patch that needs to be reverted: #8138

@jordansissel - Wont the flag just be ignored in older versions ?

[jasontedor]

@jakelandis An unrecognized VM option like that will prevent the VM from starting.
