archival: force a `CompressionError` to bytes before passing to `error.Abort`

I'm not sure what changed before pytype 09-09-2021 (from 04-15-2021), but this
started getting flagged.

This fixes:

    File "/mnt/c/Users/Matt/hg/mercurial/archival.py", line 199, in taropen: Function bytestr.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, ints: Iterable[int])
      Actually passed: (self, ints: tarfile.CompressionError)
      Attributes of protocol Iterable[int] are not implemented on tarfile.CompressionError: __iter__
