pytype: stop excluding patch.py
The underlying `email.generator.BytesGenerator` is documented as requiring an
`fp` that accepts bytes, so I'm not sure why pytype is getting confused:
File "/mnt/c/Users/Matt/hg/mercurial/patch.py", line 112, in msgfp:
Function Generator.__init__ was called with the wrong arguments [wrong-arg-types]
Expected: (self, outfp: TextIO, ...)
Actually passed: (self, outfp: io.BytesIO, ...)
