Bug 264166

When using `run-webkit-tests`, if the user has specified --verbose, --iterations > 1, and --child-processes > 1, the iteration count starts at the number of specified child processes instead of 1. EXAMPLE OUTPUT: benschwartz@computername Folder % run-webkit-tests --verbose --iterations 1000 --child-processes 10 -f --exit-after-n-failures 1 "imported/w3c/web-platform-tests/webcodecs/temporal-svc-encoding.https.any.worker.html?vp9" --force ... Found 1 test; running 1 (1000 times each: --repeat-each=1 --iterations=1000), skipping 0.
