ldap: fix Curl_ldap_version() for IBMi/OS400
- `LDAP_OPT_SUCCESS` (== 0) is missing from some LDAP implementations
  and documented to use `LDAP_SUCCESS` (== 0) instead. Use literal zero
  to avoid macro name differences.

- fix freeing `LDAP_OPT_API_INFO` buffers:
  - docs suggest `ldapai_vendor_name` on IBMi is `const char *`.
    Nothing in docs says it need to be freed.
  - `ldapai_extensions` need to be freed, according to docs.
    However, on IBMi there is `ldap_value_free()` function for it.
  Ref: https://www.ibm.com/docs/en/svd/10.0.3?topic=settings-ldap-opt-api-info

Fixing, on OS400 (V7R4M0):
```
CZM1003:  LDAP__819.c, 1028.56: CZM0045(30) Undeclared identifier LDAP_OPT_SUCCESS.
CZM1003:  LDAP__819.c, 1036.21: CZM0280(30) Function argument assignment between types "char*" and "const char*" is not allowed.
CZM1001:  LDAP__819.c, 1037.5: CZM0304(10) No function prototype given for "ber_memvfree".
...
CZS0601:  Module LDAP is not created because statement errors occurred.
```
