Do not overwrite the riscv to local copy

[myrfy001]

It seems that there is no need to overwrite riscv crate from online to local version. The local version of riscv will lead to compile error while doing make test2

Thank you! But in our envrionment, "make test2" passed.

😄 觉得没有必要删除ci中的overwirte.py中的这些

lines = []		
with open("../os/Cargo.toml", 'r') as f:		
    for line in f.readlines():		
        processed = line.replace(' git = "https://github.com/rcore-os/riscv"', ' path = "../ci-user/riscv" ')		
        lines.append(processed)		
with open("../os/Cargo.toml", 'w+') as f:		
    f.writelines(lines)

如果是为了获得更好的本地环境的测试体验，可以考虑将github的源换成gitee的源，

就像这样

lines = []		
with open("../os/Cargo.toml", 'r') as f:		
    for line in f.readlines():		
        processed = line.replace(' git = "https://gitee.com/rcore-os/riscv"', ' path = "../ci-user/riscv" ')		
        lines.append(processed)		
with open("../os/Cargo.toml", 'w+') as f:		
    f.writelines(lines)

test2的代码我就是这么尝试通过的。

现在的问题是，../ci-user/riscv这个目录下的内容本身就会导致编译失败。（至少在codespace的环境下是这样的）

上述信息的解决方案已经在最新的PR中被合并了。谢谢！
