【昇腾】MindIE服务器推理，config.json权限问题解决

问题描述：

config.json failed, by: Check Other group permission failed: Current permission is 4, but required no greater than 0. Required permission: 750, but got 644

failed to check config.json under model weight path

解决方法：

mindie服务化的配置文件也叫config.json，这个地方报错提醒了failed to check config.json under model weight path，要修改模型的config.json权限

chmod 750 config.json
