Patch ckpool: enable socket API responses

Upstream ckpool-solo stubs out send_api_response as a no-op, so the stratifier socket accepts commands like poolstats/users/workers but never writes anything back — kamado-api always gets EOF. Replace the stub with a real implementation: serialize the json_t with json_dumps, write via send_unix_msg, and free. The stratum_loop retry label handles socket cleanup.
