A VfsPosix created with a relative root path would get confused when chdir() was called on it and become unable to properly resolve absolute paths, because changing directories effectively shifted its root. The simplest fix for that would be to say "don't do that", but since the unit tests themselves do it, fix it by making a relative path absolute before storing it.
