Prevent auto-granting of location permission via DPM

Prevent the device policy client from granting the location permission
via explicit grant (setPermissionGrantState).

Unless on a managed, unattended kiosk device, the user has to explicitly
grant location-related permissions.

Location-related permissions can still be denied automatically.
