spec: do not use systemd to restart services with RefuseManualStart=true

These service unit files have RefuseManualStart=true, therefore they can
be controlled only as a dependency via the main sssd.service or socket
activation.

Resolves: #5521

:fixes: SSSD spec file `%postun` no longer tries to restart services that
  can not be restarted directly to stop produce systemd warnings
