benchmark: update iterations of benchmark/assert/deepequal-map.js

[lucshi]

Fixed: #50571

Before applying this PR, the top functions are reading test JS file, instead of real logic code of "equal".
After increasing the iteration value, the test case behaved as expected to trigger equal.

Below is the benefit after changing the iteration value. Now it reflects the real performance but brought no much overhead on execution duration.
