pytype: stop excluding wireprotoserver.py
The `config` entry is a 2 part tuple, which has `__iter__()`:
File "/mnt/c/Users/Matt/hg/mercurial/wireprotoserver.py", line 253, in _availableapis:
No attribute '__iter__' on Callable[[Any, Any], Any] [attribute-error]
In Union[Callable[[Any, Any, Any, Any, Any], None], Callable[[Any, Any], Any]]
