default to tokio-epoll-uring in CI tests & on Linux (#7077)

Browse Source 
All of production is using it now as of
https://github.com/neondatabase/aws/pull/1121

The change in `flaky_tests.py` resets the flakiness detection logic.

The alternative would have been to repeat the choice of io engine in
each test name, which would junk up the various test reports too much.
