    useradd-staticids.bbclass: trigger reparsing when table files change
    
    This addresses (among others) the following problem:
    - USERADD_ERROR_DYNAMIC=error causes a recipe to get skipped
      because a static ID entry is missing
    - the entry gets added to the file
    - using the recipe still fails with the same error as before
      because the recipe gets loaded from the cache instead
      of re-parsing it with the new table content
