Silence confusing messages if Upstart is installed but not active

  * openssh-server.postinst: Quiesce "Unable to connect to Upstart" error
    message from initctl if upstart is installed, but not the current init
    system. (LP: #1440070)
  * openssh-server.postinst: Fix version comparisons of upgrade adjustments
    to not apply to fresh installs.
