Fix sysvinit script crash and not working, fixed tatsushid#8

* the real process is a perl process as xplained in
  h2o/h2o#84 (comment)
  so we need to point in the start-and-stop-daemon to property
  managed.. so in init scritp is commented and fixed the functions
* starts a set of superdaemon program (named start_server) and a
  support library written in Perl, for hot-deploying TCP servers
  so the provided init script does nothing cos does not point real process
