Only untrusted apps had privilegs to read file descriptors passed in
from traceur, which was an oversight. This fixes the policy so that priv
apps can also access file descriptors from traceur in order to read
reports shared from traceur.

Bug: 74435522
Test: better bug has access to reports shared from traceur
