prebuilts: update build scripts and updater-scripts for config name change.

This is being changed to fix bug with qcom-post-boot.sh overriding our gov
settings. This is used in conjunction with a modification to the ramdisk to
add a service called chronic-config that is started after qcom-post-boot.

The config script is now located at: /system/etc/chronic-config.sh
