Add /vendor/odm/overlay to framework RRO allowlist

Framework RROs were allowed in vendor or odm partition.  However, they
were not allowed the odm subdirectory of the vendor partition which is
used by devices without a separate odm partition.  This difference was
not intended so add the /vendor/odm/overlay path to the allowed list.
