Change start on event to init-boot-done

:Release Notes:
second-screen-service, com.pal.app.settings and
com.webos.app.installation depend on the files created by nyx-utils, so
nyx-utils must be started soon enough to provide these.

:Detailed Notes:
Currently nyx-utils starts much earlier than it needs to, so we will
move the start on to init-boot-done.  As the three programs above
depend on the files built by nyx-utils, they will need to have a start
on dependency of "stopped nyx-utils" 'and'ed with their current start
conditions.
Also take this opportunity to remove the old Upstart 0.3 file.

:Testing Performed:
Local build - verify that nyx output files are created properly

:QA Notes:

:Issues Addressed:
[GF-46288] Move start-on event for nyx-utils.conf to init-boot-done
