(Includes the change in #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: #34727

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • commit message follows commit guidelines

test: remove error message checking in test-worker-init-failure
5cf4c45 
Let the check for the error code suffice and don't check for a
particular string in the message.

Fixes: nodejs#33759

Do we know why the test is sensitive to resource constraints?

I'm guessing because it opens a lot of files (128).

An alternative we could experiment with is halving all the hard-coded numbers.

IMO the sensitivity to resource constraints is by design in the test, and it actually helped (and helps) to detect unforeseen control paths that are not covered in code and test, so is best placed to run in /parallel.
