Hang up on llama-server at once when a reply is stopped

A stop was noticed at the reply's next chunk, and llama-server stops a
task only when its client hangs up. Through a long prompt pass, measured
at 12232 tokens for a file with page images, no chunk comes, so the GPU
kept working after Stop until the first one. interrupt() now shuts the
reply's socket from the stop handler; the request goes through
http.client, which exposes it. A fake server that stays silent records the
hang-up within a second of the stop.
