Subject: [PATCH] test: make http2 close-while-writing single-shot

The test only needs one request data chunk to queue the server write
and destroy the client stream. Using a persistent data listener can
queue multiple writes and multiple destroys from the same request body,
which makes the test occasionally hang until the harness timeout.
