Subject: [PATCH] DO NOT MERGE: Allow Ephemeral apps to load code from
/data/data for 8.0
This restriction causes issues with dynamite.
Since untrusted_v2_app was about enforcing this constraint put installed
v2 applications back into the normal untrusted_app domain.
CP from commit fe836817942f21eaf6a33f137ea56eb1329d29fe & adapts for 8.0
Bug: 64806320

Test: make cts
