D7517: filemerge: byteify the open() mode

REVISION SUMMARY
  This is actually `pycompat.open()`, so it need bytes.  It regressed recently on
  default.
  
  VSCode flagged some invalid mode to open() the other day, but I don't remember
  where.  That's what got me searching in this area.  I'm almost certain that it
  was the other way (i.e. saying open doesn't take bytes), but I can't find that
  now.
