http: add test for Retry-After handling

When enabling Acquire::Retries::HandleRetryAfter, the value of the
Retry-After http header is honored and the retry is not executed earlier
than this point in time (except if that is longer than the max delay
time). The added test checks if the request is delayed at least by the
requested time.
