Fixing permission for Biometric Logos in CredMan

The issue is thoroughly documented in the bug, but this change ensures
that the biometric logo setting can be done. There is strange behaviour
with 'signature|privilege' where the new 'privilege' scope appears to
break the 'OR' relationship for our framework UI codebase.

Now, we've added the framework UI package within the privapp allowlist
for that single permission.
