[issue20425] inspect.Signature should work on decorated builtins

[Yury Selivanov]

New submission from Yury Selivanov:

inspect.signature should work with decorated builtins. Suppose I want to create a cached version of 'min' builtin:

   cached_min = functools.lru_cache()(min)

The signature of the 'cached_min' should match the signature of 'min'.

The patch is attached.
