    kyua: Try harder to delete directories.
    
    When recursing into a directory to delete it, start by chmod'ing it to
    0700.  This fixes an issue where kyua is able to run, but not debug, a
    test case that creates unwriteable directories, because when debugging
    it tries (and fails) to delete the directory after the test completes.
