bugfix: make test case right

[fuweid]

1. fix format issue for go1.10 --> fix Go 1.10: spdy_bench_test.go:63: Fatalf format %s reads arg #1, but call has only 0 args #72
2. update the github.com/docker/spdystream/... package test case --> fix ./ws_test.go:27:15: too many arguments in call to conn.Serve #71

@dmcgowan could we add the CI for this repo, like travis-CI? This repo is pretty cool but it needs tool for review. How do you think about this? 😄
