encoding: force a few Errors to bytes before passing to `error.Abort`

I'm not sure what changed before pytype 09-09-2021 (from 04-15-2021), but these
started getting flagged.  PyCharm also flagged these.  This fixes the following:

    File "/mnt/c/Users/Matt/hg/mercurial/encoding.py", line 243, in fromlocal: Function Abort.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, message: Union[bytearray, bytes, memoryview], ...)
      Actually passed: (self, message: LookupError, ...)
    File "/mnt/c/Users/Matt/hg/mercurial/encoding.py", line 309, in lower: Function Abort.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, message: Union[bytearray, bytes, memoryview], ...)
      Actually passed: (self, message: LookupError, ...)
    File "/mnt/c/Users/Matt/hg/mercurial/encoding.py", line 336, in upperfallback: Function Abort.__init__ was called with the wrong arguments [wrong-arg-types]
             Expected: (self, message: Union[bytearray, bytes, memoryview], ...)
      Actually passed: (self, message: LookupError, ...)
    Called from (traceback):
      line 391, in current file
      line 348, in get
      line 318, in upper
