test: move test-worker-init-failure to sequential
(Includes the change in https://github.com/nodejs/node/pull/34727 to avoid subsequent merge conflict. This supplants it.)
Unfortunately, the test is sensitive to resource constraints and is unreliable on macOS in CI when in parallel.
Fixes: https://github.com/nodejs/node/pull/34727
