[Bug]: origRealpath in fs patch is not the original fs.realpath

[fa93hws]

What happened?

In the fs patch, it's assumed that methods in fs is independent, so original fs methods before patched are still accessible:

const origReadlink = fs.readlink.bind(fs);
const origRealpath = fs.realpath.bind(fs);

However that's not the case, and it can be easily reproduced via running the following code snippet:

const fs = require('fs');
fs.readlink = () => {
  throw new Error('123');
}
fs.realpath('<some smybolic link>', (err, out) => {
});

which throws an error:

> Uncaught Error: 123
    at fs.readlink (REPL19:1:29)
    at node:fs:2908:10
> 

That indicates that the behaviour of origRealpath has been changed as soon as readlink got patched! And it can lead to sandbox escape from here.
In my case, origRealpath returns something in the bazel out directory which is again a symlink, and origReadlink later resolves it to something in my source directory.

Version

Only nodejs version matters:

Node.js v20.12.2
