    bitbake: tinfoil: fix get_recipe_file() to return an error on invalid recipe
    
    This function calls cooker.findBestProvider() but didn't handle the fact
    that that function returns a tuple (None, None, None, None) when there
    is no matching recipe. (This fixes devtool in OpenEmbedded showing a
    traceback when an invalid recipe is specified instead of a proper error
    message.)
