examples: use do/while loop for multi examples

It's conceivable that after the first time curl_multi_perform returns,
the outvalue still_running will be 0, but work will have been done. This
is shown by a workload of small, purely file:// based URLs. Ensure that
we always read pending messages off the multi handle by forcing the
while loop to run at least once.
