Complete tests for OS hardening

[schurzi]

Description

Our current testcase does not fully support arch linux.

Solution

We want to adapt the test in a way, that supports these linux flavors.

Alternatives

• find a more general way to handel auditd restarts
• create a second handler for arch (or a separate for RHEL)

Additional information

The current test breaks on restart of audit (https://github.com/dev-sec/ansible-collection-hardening/actions/runs/4664154817/jobs/8256129393)

the cause for this should be our RedHat workaround:
