Fixes and improvements of the new startup scripts:

Fixes and improvements of the new startup scripts:
- better upgrade from EMI-2 (changed pidfiles location)
- better upgrade from EMI-3 (changed startup scripts)
- shutdown old daemon in start action of proxy interlogger (process changed the name)
- moving pidfiles rather in postinstall scripts (deb, rpm)
- rpm:
  - proper /var/lock/subsys location in legacy script glite-lb-locallogger
  - use pidfiles to kill (there were problems with shutting down bkserver)
- deb:
 - better info messages when startup is disabled
- always use distro-specific startup scripts (package-less deployment)
