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.
