Switch to new unified layout for Upstart jobs as documented in

https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
checks for a running Upstart, and we now let dh_installinit handle most
of the heavy lifting in maintainer scripts.  Ubuntu users should be
essentially unaffected except that sshd may no longer start
automatically in chroots if the running Upstart predates 0.9.0; but the
main goal is simply not to break when openssh-server is installed in a
chroot.
