Stephen Smalley dc88dca115 Get rid of separate platform_app_data_file type.
The original concept was to allow separation between /data/data/<pkgdir>
files of "platform" apps (signed by one of the four build keys) and
untrusted apps.  But we had to allow read/write to support passing of
open files via Binder or local socket for compatibilty, and it seems
that direct open by pathname is in fact used in Android as well,
only passing the pathname via Binder or local socket.  So there is no
real benefit to keeping it as a separate type.

Retain a type alias for platform_app_data_file to app_data_file until
restorecon /data/data support is in place to provide compatibility.
