    libcheese: effects: don't print CRITICAL errors if directory doesn't exist
    
    Applications should use cheese_effect_load_effects to load the default set of effects.
    
    cheese_effect_load_effects() calls
    cheese_effect_load_effects_from_directory() with a list of predefined
    places to search for effects. Some of those directories may not exist.
    
    cheese_effect_load_effects_from_directory() shouldn't emit CRITICAL
    messages in this condition.
