errors: remove unnecessary varargs handling from OutOfBandError

In my recent D10465, I moved some code over from scmutil into
`OutOfBandError.__init__`. The code was written to deal with an
arbitrary number of `message` arguments to the constructor. It turns
out that we only ever pass 0 or 1. Given that, let's simplify it.
