fix: make sure directory for async is correctly set

[gardar]

In certain cases where the home directory environment variable ($HOME) is set and it doesn't match the home directory in /etc/passwd the async_status task will fail with a message such as:

"results_file": "/home/runner/.ansible_async/25596
1675523.4961", "started": 1}, "msg": "could not find job", "results_file": "/root/.ansible_async/255961675523.4961"

This fixes that issue by setting the HOME environment variable as the ansible_async_dir variable that 'async_status' task accepts as a override.

I ran into this issue with the creator-ee container that is supposedly going to be fixed but I'm proposing this change as this issue could still occur in other containers/environments.

Any chance we could get this one merged too @ssbarnea ?
