Tests: adjusted proxy_cache_use_stale.t cache validity.

At least the "s-w-r - updating stale" test sometimes fails on slow
hosts due to "stale-while-revalidate=4" being not enough, so the request
returns with the EXPIRED cache status instead of STALE.

Fix is to use larger "stale-while-revalidate=" times where it is not
significant.
