Fix issues with ansible-playbook-callbacks test (#82407)

The timing of the async tasks was a little unpredictable, meaning that
sometimes we would get an unexpected number of v2_runner_on_async_poll
callbacks, and fail the test. This change fixes the issue by increasing
the poll interval to 2 seconds and the sleep duration to 3 seconds, such
that on a reasonably responsive system we will poll twice per task, with
the sleep ending in the middle of the two polls.

The include_me.yml file does not exist in this integration test. It has
been added.

The remote_tmp_dir.path expression is invalid - the setup_remote_tmp_dir
role uses set_fact to set remote_tmp_dir to remote_tmp_dir.path.

The integration tests run with ANSIBLE_HOST_PATTERN_MISMATCH=error,
meaning that the final play was never reached. Set
ANSIBLE_HOST_PATTERN_MISMATCH=warning to continue past the play and
trigger the v2_playbook_on_no_hosts_matched callback.
