    lib/bb/cooker.py: fix for BBFILE_PATTERN = ""
    
    There would be error when BBFILE_PATTERN = None:
      BBFILE_PATTERN_foo not defined
    
    This is the correct behaviour, but when the layer sets BBFILE_PATTERN = "",
    it would match all the remaining recipes, and cause "No bb files matched BBFILE_PATTERN"
    warnings for all the layers which behind it.
    
    When a layer sets BBFILE_PATTERN = "" (for example, a layer only
    provides git repos and source tarballs), now it means has no recipes.
    This is different from BBFILE_PATTERN_IGNORE_EMPTY, the later one means
    that it *may* not have any recipes.
