Only allow preinstalled application to be able to call setHotwordDetectionServiceConfig

We added a new permission "MANAGE_HOTWORD_DETECTION" to allow
the application that held this permission to be able to use
setHotwordDetectionServiceConfig functions.

In order to avoid the feature leakage, we submit the change
about Shell in internal branch.
