    Fix input race condition in t_skew.py
    
    In two of the kinit tests run by t_skew.py, we expect kinit to exit
    before reading the password.  If we supply a password input for those
    commands, we can fail with a broken pipe exception if the master
    process tries to write the password after the slave process exits.
    
    Also correctly check the output of the last kinit invocation.
