test: wait_for_examine and delay in reap_unregistered_poller.sh

Browse Source 
We need to give the thread library some time to reap
the unregistered poller - it is a bit of a delayed
process.  We have to wait for examine to finish on
the aio bdev, then the poll group gets destroyed and
the pollers unregistered.  This marks the pollers as
UNREGISTERED, but they aren't actually reaped until
next time the thread is polled.

Fixes issue #2980.
