ensure Cnf::FindFile doesn't return files below /dev/null
Very unlikely, but if the parent is /dev/null, the child empty and the grandchild a value we returned /dev/null/value which doesn't exist, so hardly a problem, but for best operability we should be consistent in our work and return /dev/null always.
