Nick Kralevich 2aa727e3f0 DO NOT MERGE: Flip FORCE_PERMISSIVE_TO_UNCONFINED to true 
Force any experimental SELinux domains (ones tagged with
"permissive_or_unconfined") into unconfined. This flag is
intended to be flipped when we're preparing a release,
to eliminate inconsistencies between user and userdebug devices,
and to ensure that we're enforcing a minimal set of rules for all
SELinux domains.

Without this change, our user builds will behave differently than
userdebug builds, complicating testing.
