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.
