webos-image: modifying Upstart 1.8 files only

:Release Notes:
Fix bugs in upstart 1.8 scripts.

:Detailed Notes:
Configurator configures db, filecache and activitymanager.
There are two upstart scripts for the roles.
 1. configurator.conf : db, filecache
 2. configurator-async.conf : activitymanager
I modified both scripts for their one jobs.
In addition, because upstart 1.8 scripts are copied from old one,
there are keyword bug. I fixed it.

* configurator       50  ->  51

  a54e2d9 Modify Upstart 1.8 job files

:Testing Performed:
I tested MiniBAT in local build.
Those upstart scripts are installed when upstart 1.8 is enabled.
Therefore, it cannot be tested using validation images.

:QA Notes:
There are no known QA issues as the files being modified with this fix are
not going to be actually used until we turn on Upstart 1.8

:Issues Addressed:
[GF-5620] update coreOS upstart scripts for 1.8
[GF-10057] MiniBAT failed: Launch Calendar app and confirm that it launches successfully.
[GF-11829] CCC: configurator=51
