Fix broken remediation in file_ownership_var_log_audit_stig

[jan-cerny]

The chown command contained duplicate directory path, which caused that the file woner on the log file wasn't changed.

In addition, enable Ansible remediation for this rule on RHEL.

Fixes: #15129

Review Hints:

• Run automatus tests for the rule file_ownership_var_log_audit_stig before and after this change, with both Bash and Ansible.
