typing: add a fake `__init__()` to bytestr to distract pytype

I'm not sure what changed before pytype 09-09-2021 (from 04-15-2021), but these
started getting flagged.  This wrapping an exception in a `bytestr` pattern has
been flagged before, and I've fixed it then with `stringutil.forcebytestr()`.
But that doesn't work here, because it would create a circular import.

I suspect the issue is `bytes.__new__()` wants `Iterable[int]`, so it just
assumes the subclass will also take that.  The referenced pytype bug isn't an
exact match, but seems related and the suggested workaround helps.

The specific warnings fixed are:

    File "/mnt/c/Users/Matt/hg/mercurial/encoding.py", line 212, in tolocal: Function bytestr.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, ints: Iterable[int])
      Actually passed: (self, ints: LookupError)
      Attributes of protocol Iterable[int] are not implemented on LookupError: __iter__
    Called from (traceback):
