Fix PKCS#11 token slot and object label issues

- Use --free for token initialization (SoftHSM assigns slots dynamically)
- Fix object labels to match test expectations:
  - rdkclient (cert) and rdkclient-key (key) at ID 0x01
  - rdkclient-p12-key (key) at ID 0x2c for P12 patch testing
- Import script already handles dynamic slot lookup correctly
- Aligns with ssa-cpc and rdkfwupdater test configurations
