test: disable core dumps before running crash test

The test spawns a subprocess with the `--abort-on-uncaught-exception`
flag and expects it to terminate with a SIGABRT signal.

On systems where core dumps are enabled, that actually generates an
unnecessary core dump. Set `ulimit -c 0` before spawning the subprocess.

Fixes: nodejs#29286
