            Log:
            add basic test which covers systemd-mountfsd

Recently, the systemd-mountfsd program/service got confined by SELinux.
Purpose of this automated test is to cover the basic scenarios in
which the daemon is used. The systemd-mountfsd man page was used as
the source of test scenarios/ideas.
