[PATCH BlueZ] profile: Add exception from being claimed internally

[PATCH BlueZ] profile: Add exception from being claimed internally

[Sonny Sasaka]

This adds a flag to give exception to profiles that are considered safe
to be both handled internally and externally via GATT API. Currently
this includes the battery profile.
