auditvfs: forward options property from nested vfs

This was breaking my ability to use treemanifests in bundlerepos, and
was deeply mysterious. We should probably just make the options
property a formal part of the vfs API, and make it a required
construction parameter. Sadly, I don't have time to dive into that
refactor right now.
