Michael Eischer 9a99141a5f fs: remove os.FileInfo from fs.ExtendedFileInfo
Only the `Sys()` value from os.FileInfo is kept as field `sys` to
support Windows. The os.FileInfo removal ensures that for values like
`ModTime` that existed in both data structures there's no more confusion
which value is actually used.
