test: deflake test-http2-empty-frame-without-eof

It may happen that the data in `emptyframe.http2` reaches the client even before the client has started sending the request, causing an `ERR_HTTP2_STREAM_ERROR` instead. Fix this by making sure the frame is not sent until some data reaches the server.
