This work-around is no longer necessary as the default Fedora policy now
covers the Samba DC daemon. It never really worked correctly, anyway,
because Samba doesn't start `winbindd` fast enough for the
`/run/samba/winbindd` directory to be created before systemd spawns the
`restorecon` process, so it would usually fail to start the service the
first time after a reboot.
