`stat` on directory returns weird timestamps

[Arshia001]

Steps to reproduce:

• run WinterJS with: wasmer run build/winterjs-st.wasm --net --mapdir /app:tests -- /app/simple.js --single-threaded
• simple.js should call createRequire('/app/simple.js')
• this ends up calling tokio::fs::metadata on /app
• the timestamps returned are: 1730106167038906518, 1730106167038906518, 1730106167038906518 (for ctim, mtim, atim)

It should be possible to recreate the issue by just calling metadata on a folder that's the root of a mounted FS tree, but I haven't verified this.
