vfs: add a `_auditpath` to abstract vfs

We are about to make `rename` audit path. Since rename lives in the
`abstractvfs` layer, we need it to be aware of auditing to some extent.

The default implementation is no-op because multiple existing vfs are not using
auditing at all right now (eg: fncachevfs).
