Change the vnode tests to use the current directory when creating temporary files, which we can assume is a volatile work directory, and then make the kqueue_test.sh driver _not_ abandon the directory created by Kyua. This makes the various kqueue tests independent of each other, and ensures the temporary file is cleaned up on failure. Problem spotted by asomers@ when reviewing D4254.
