            Log:
            add a basic test which covers systemd-nsresourced

Recently, the systemd-nsresourced program became confined by SELinux.
Purpose of this TC is to test the basic systemd-nsresourced scenarios.
The TC looks for appropriate policy rules and file context patterns.

The TC covers BZ#2290477.
