Fix P12 patch: Add token label to PKCS#11 URI to prevent uninitialized slot scanning

- Updated PKCS#11 URI from 'pkcs11:id=%02x;type=private' to 'pkcs11:token=RDK_TOKEN;id=%02x;type=private'
- This prevents libp11 from scanning uninitialized SoftHSM slots which caused 'passed a null parameter' errors
- Fixes issue where curl failed with reference P12 files containing sentinel keys
- Works for both SoftHSM test environment and production OP-TEE hardware HSM
