Drop special handling of app_data_file in mls constraints.

This was a legacy of trying to support per-app level isolation
in a compatible manner by blocking direct open but permitting
read/write via passing of open files over Binder or local sockets.
It is no longer relevant and just confusing to anyone trying to use
the mls support for anything else.
