RunnerGenAllGraph4Callee#doCombineClassFile结果合并会清空原文件

最后会调用JavaCGFileUtil.class#genBufferedWriter public static BufferedWriter genBufferedWriter(String filePath) throws FileNotFoundException { return new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath), StandardCharsets.UTF_8)); }

应该写成 new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath, true), StandardCharsets.UTF_8));

最新的版本没有做合并的处理了，还同提交，我改一下这个方法，支持指定是否覆盖
