[stable-2.9] Fix ansible-test integration temp dir location.

Previously the temporary directory used to run integration tests resided under the user's home directory. This prevented ansible-playbook from detecting the default collection when running tests.

Now the temporary directory is created within the collection to facilitate default collection detection.
(cherry picked from commit 4c79f1ec4d)
