oracle template: fix lxc-shutdown with upstart SIGPWR handler

Browse Source 
OL6 uses upstart init and needs a handler for the SIGPWR that
lxc-shutdown sends it so that a container can shut down cleanly.

# upstart, so we create an upstart job to handle SIGPWR to shut down
# cleanly. We use "init 0" instead of shutdown -h now to avoid SELinux
# permission denied when upstart's shutdown tries to connect to the
