    bitbake: cooker: Track directories searched for bbappend/bb files
    
    Some of the directories searched by BBFILES are not currently being added
    to the inotify watch list. This can mean that added append files are not
    noticed leading to misleading metadata results when using
    BB_SERVER_TIMEOUT != 0.
    
    We use glob to expand the BBFILES references and without writing our own
    implentation, figuring out the directories it searches is hard. We use
    some horrible hacks here to intecept the listdir calls, I'm open
    to better ways to handle this but this does ensure we have the right
    watches set.
