aio-posix: fix io_uring with external events
When external event sources are disabled fdmon-io_uring falls back to
fdmon-poll. The ->need_wait() callback needs to watch for this so it
can return true when external event sources are disabled.
It is also necessary to call ->wait() when AioHandlers have changed
because io_uring is asynchronous and we must submit new sqes.
Both of these changes to ->need_wait() together fix tests/test-aio -p
/aio/external-client, which failed with:
test-aio: tests/test-aio.c:404: test_aio_external_client: Assertion `aio_poll(ctx, false)' failed.
