Fix privileged permission handling for ODM apps.

SystemConfig mentioned ODM is just another vendor partition and reads
ODM privileged permission allowlist XML files into the vendor allowlist,
so we should handle vendor apps and ODM apps in the same way.

This is the same thing as aosp/2873695 for the new subsystem.
