test: widen the gap in the resolver maxTimeout comparison

test-dns-resolver-max-timeout times a query with `{ timeout: 500,
tries: 3 }` against one that also sets `maxTimeout: 500` and asserts
the first took longer. c-ares only expires a try when cares_wrap's
timer fires, every `timeout` ms, so each try costs one or two ticks
depending on sub-millisecond ordering, and uncapped retries also get
0.5-1x jitter. That leaves the capped run anywhere in 1500-3000 ms and
the uncapped one in 3000-4500 ms; on a busy rhel10-ppc64le host both
came out at 3005 ms. With `timeout: 100, tries: 5` the ranges (about
600-1000 ms and 5000-7500 ms measured under load) cannot meet.
