tty.isatty() reports wrong results for opened files #32995
Description
The result seem to be correct for fd 0, 1 and 2 but wrong for files that are opened later.
The following sample shows how the results differ from node and bun:
$ cat test.js
var tty = require('node:tty');
var fs = require('node:fs');
console.log(tty.isatty(0));
console.log(tty.isatty(1));
console.log(tty.isatty(2));
var fd1 = fs.openSync('/dev/stdin', 'r')
var fd2 = fs.openSync('/dev/stdout', 'w')
var fd3 = fs.openSync('/dev/stderr', 'w')
console.log(tty.isatty(fd1));
console.log(tty.isatty(fd2));
console.log(tty.isatty(fd3));

I noticed this while running the emscripten test suite under deno.
