  Fix astcanary startup problem due to wrong pid value from before daemon call
  
  When Asterisk forks itself into the background via a call to daemon, it must
  re-set the pid value of the new process. Otherwise, astcanary gets the pid
  value of the process before the fork, which prevents it from running. Asterisk
  eventually starts lowering its priority, as it can no longer communicate
  with the proverbial canary in the coal mine.
  
  This patch ensures that the correct process identifier is used by astcanary.
  
  Note that this is getting committed to 10 as a regression fix.
