Fix openpbs integration test timing out

[jonathan-eq]

This commit fixes the issue where our mocked qdel bineries fails if the job has already finished (i.e - it was already killed by the TERMINATE_MSG over zmq), and would retry for 30 seconds. This was visible in "test_openpbs_driver_with_poly_example_failing_poll_fails_ert_and_propagates_exception_to_user"

Approach
Short description of the approach

(Screenshot of new behavior in GUI if applicable)

• PR title captures the intent of the changes, and is fitting for release notes.
• Added appropriate release note label
• Commit history is consistent and clean, in line with the contribution guidelines.
• Make sure unit tests pass locally after every commit (git rebase -i main --exec 'just rapid-tests')

When applicable

• When there are user facing changes: Updated documentation
• New behavior or changes to existing untested code: Ensured that unit tests are added (See Ground Rules).
• Large PR: Prepare changes in small commits for more convenient review
• Bug fix: Add regression test for the bug
• Bug fix: Add backport label to latest release (format: 'backport release-branch-name')

I mocked some of the batching timeouts to be smaller (as we are only running two realizations anyways, this should be fine)
The test time changed 32s -> 2.5s. This probably started happening as a side effect of introducing batch killing jobs, but it is strange cod speed did not pick this up 🤔
