Fix intermittent sslapitest early data related failures

Fix intermittent sslapitest early data related failures

Early data is time sensitive. We have an approx 8 second allowance between
writing the early data and reading it. If we exceed that time tests will
fail. This can sometimes (rarely) occur in normal CI operation. We can try
and detect this and just ignore the result of such test failures if the test
has taken too long. We assume anything over 7 seconds is too long.

This is a partial fix for #22605
