Fix some tests (#3100)

* Sleep for one millisecond in the handler because the `Latency` will return `0s` sometimes and the test will fail

* The `TCPListener.File` is not supported by windows, it is unimplemented now

* Remove the `LF` in the `testdata/template/raw.tmpl`, because if set the git config `core.autocrlf=true`, will append `CR` to the raw.tmpl automatically, then test is failed on Windows
