py/modbuiltins: In built-in dir make use of mp_load_method_protected.

Browse Source 
This gives dir() better behaviour when listing the attributes of a user
type that defines __getattr__: it will now not list those attributes for
which __getattr__ raises AttributeError (meaning the attribute is not
supported by the object).
