Stop setup.py installing specific init.d script
Stop setup.py installing specific init.d script

- it is very RedHat/Centos/SL specific and whereas the setup.py script
  is meant to be a more general way of installing ssm
- it also seems to cause problems with fpm and the packages generated
  by pleaserun as the bad init script conflicts with the unit files
- add a note saying this script does not install init scripts
