tasks: Add missing tags for async tasks

When running the role using a specific tag (eg -t auth), some tasks
try to check the status of the async ones and they fail because the
async task was never executed due to missing the 'always' tag. We can
fix that by adding the missing tags to the async tasks.

For example,

TASK [ansible-hardening : Remove .shosts or shosts.equiv files]
******************************************************************************************************************************
fatal: [localhost]: FAILED! => {"failed": true, "msg": "'job_result' is undefined"}

So we add the appropriate tags to the async tasks.
