Reduce scope (and running time) of sync-repeated-and-caching test.

Synchronous XMLHttpRequest fetches are slow end-to-end when running
LayoutTests, particularly on Windows. The range of requests issued by
xmlhttprequest/sync-repeated-and-caching really doesn't have to be
that extensive to catch regressions. Hence, reduce scope somewhat.
