http: setEncoding override for incoming packets

added override to socket.setEncoding to not allow encoding changes for
incoming HTTP requests
added tests to ensure method throws JavaScript error
because an HTTP buffer must be in US-ASCII, this function should not
be allowed and should throw an Error
currently, the process encounters a fatal v8 error and crashes
