Reworked by rearranging agl-systemd's recipe

The current AGL is running the process as root user. Therefore,
there is no need to configure the capability. This patch changes
the script to not run the capability setting. I'm not sure if
these scripts are working as expected now. Toyota will not
implement the capability settings this time. This will be worked
out in future Production Readiness activities.
