Start tracking platform/vendor data access violations

As part of Treble, enforce that the communication between platform
and vendor components use the official hw binder APIs. Prevent sharing
of data by file path. Platform and vendor components may share
files, but only via FD passed over hw binder.

This change adds the violators attribute that will be used to mark
violating domains that need to be fixed.
