Allow camera to notify traced of a notable event (marlin/sailfish)

Most apps already have the permission to act as full producers
(isolated_app, ephemeral_app, priv_app, untrusted_app_all), but
the camera doesn't inherit that as it runs in its own domain.

Granting only the socket (i.e. ipc) permission, as:
* only that is needed at the moment.
* granting the shmem/fd permissions would require a broader change, as traced_tmpfs is declared in private/.

Specific denial:
