Reproduction of Deno issue when stat-ing symlinks on Linux

Reproduction of issue with Deno.stat[Sync] and Deno.lstat[Sync] on symlinks

Deno Repository Issue: denoland/deno#17723

To reproduce the issue, run deno task run (or execute deno run --allow-read --allow-write example.ts)

This code directly creates a (hard) link pointing to example.ts and then immediately tests if that file is a symlink, and reports that it is not. You can do the same with a manually created symlink (since Deno.link[Sync] creates hard links):

# assuming you test from a not-Windows machine
ln -sf $PWD/example.ts $PWD/symlink.ts
deno eval "console.log(Deno.statSync('symlink.ts').isSymlink)"
deno eval "console.log(Deno.lstatSync('symlink.ts').isSymlink)" # <-- this one *does* produce the correct result

and observe that, again, isSymlink on the resulting FileInfo object is false.
