    Fix filesystem permission masks

    The setuid bit is ignored on directories, so it's not necessary
    to remove it. The tasks currently remove the user's ability to
    use their home directory.

    The patch fixes the permissions problem, ensures that the 'nobody'
    user is skipped, and enables testing for the tasks in the gate.
