pycompat: fix bytestr(bytes) in Python 3.11

In Python 3.10, the `bytes` type itself does not have a `__bytes__`
attribute, but it does in 3.11. Yet `bytes(bytes)` does not give
the wished output, so we have to add an exceptional case.

The added case in the doctest reproduces the problem with Python 3.11.

Impact: error treatment in expressions such as `repo[b'invalid']` gets
broken.

from typing import (
    List,
)

version: int

class mpatchError(Exception): ...

def patches(text: bytes, bins: List[bytes]) -> bytes: ...
def patchedsize(orig: int, data: bytes) -> int: ...
