dnsdist: Reply to HTTP/2 PING frames immediately

We usually buffer a bit to avoid sending a lot of small data chunks
on the wire (or to the kernel anyway), but for `HTTP/2 PING` frames
that are not followed by anything else calling for a response, this
causes an issue as these frames are designed to measure the latency
between a client and a server, and are used by HTTP/2 proxies to
ensure that a connection can be reused.

(cherry picked from commit 4170083b33b171b150257311ef832c743f4d32c6)
