Start locking down access to services from ephemeral apps

This starts with the reduction in the number of services that
ephemeral apps can access. Prior to this commit, ephemeral apps were
permitted to access most of the service_manager services accessible
by conventional apps. This commit reduces this set by removing access
from ephemeral apps to:
* gatekeeper_service,
* sec_key_att_app_id_provider_service,
* wallpaper_service,
* wifiaware_service,
* wifip2p_service,
* wifi_service.

Test: Device boots up fine, Chrome, Play Movies, YouTube, Netflix, work fine.
