fs: after unlink() of locked file, readdir() still shows the file

[bpasero]

On Windows, when a file is locked by another process, you can still unlink() this file from another node process and the operation will not fail. The reason has been explained in good detail in #7164.

After unlink() has been called on the locked file, I would expect that a call to readdir() on the parent of that file would not show this file in the list. But the file still shows up although it has been unlinked before. Consistent behavior would be to not list this file.

@bpasero You've opened several of these (#7174, 7175). Would you mind creating a PR with applicable tests of how you'd expect these operations to work?

Thanks @bpasero for opening these. I ran into this today. It's surprising behavior for fs.readdir to show a file that fs.unlink has just deleted.
