Unify permissions under UPDATE_DEVICE_STATS.

Browse Source 
The UPDATE_DEVICE_STATS permission has become the de-facto mechanism
that platform components use to shift blame for resource usage, so
it's confusing to also have a separate MODIFY_NETWORK_ACCOUNTING
permission.  So this change replaces MODIFY_NETWORK_ACCOUNTING with
UPDATE_DEVICE_STATS.
