    bitbake: cooker.py: Fix layer priority processing
    
    If you have a layer with a blank BBFILE_PATTERN the layer was ignored
    when processing the list of layers with priorities.  This list is not
    only used for processing recipes, but also by additional programs such
    as bitbake-layers show-layers.
    
    Without this change, a layer that provides configuration or classes
    only does now show up in show-layers, which is used by the
    yocto-compat-layer.py script.  This causes a failures in the compatibility
    check.
