Add bash-color-prompt and anaconda-webui to critpath
    
    anaconda's webui has been split out into a separate source
    package, so we need to list it separately in the critical path.
    
    I also suggest bash-color-prompt should be treated as critical
    path. This will ensure it gets gated by openQA (so we can adjust
    openQA to handle changes to the prompt before they break almost
    every test for every update), but also it just makes sense: the
    package is setting the default prompt, which could cause all
    kinds of problems if there is a bad update to it.
