benchmark: update iterations in benchmark/crypto/aes-gcm-throughput.js
Refs: https://github.com/nodejs/node/issues/50571
Below is score improvement from 500 to 2500, measured on Cascake server. Improvement can be a bit more if changing to 5000 but the running time will be notable longer than appropriate duration.
To make it clear, I will submit more PRs one by one to address each case in crypto, and tracked by 50571 issue.
