parser: force a `ValueError` to bytes before passing to `error.ParseError`

I'm not sure what changed before pytype 09-09-2021 (from 04-15-2021), but this
started getting flagged.  I think there's a pytype bug here, because I don't
see how `.lower()` can be getting called on a `ValueError` after it is forced to
a byte string.  That's suppressed for now to make progress.

This fixes:

    File "/mnt/c/Users/Matt/hg/mercurial/parser.py", line 219, in unescapestr: Function bytestr.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, ints: Iterable[int])
      Actually passed: (self, ints: ValueError)
      Attributes of protocol Iterable[int] are not implemented on ValueError: __iter__
    File "/mnt/c/Users/Matt/hg/mercurial/parser.py", line 219, in unescapestr: No attribute 'lower' on ValueError [attribute-error]
      In Union[ValueError, mercurial.pycompat.bytestr]
