pathutil: mark parent directories as audited as we go
Before
0b7ce0b16d8a (pathauditor: change parts verification order to
be root first, 2016-02-11), we used to validate child directories
before parents. It was then important to only mark the child audited
only after we had audited its parent (ancestors). I'm pretty sure we
don't need to do that any more, now that we audit parents before
children.
