Get rid of the `authHook` parameter on `processConnection`

This is (morally) dead code.

As @edolstra pointed out in
https://github.com/NixOS/nix/pull/5226#discussion_r1073470813, this is
no longer needed.

I created this in 8d4162ff9e940ea9e2f97b07f3030a722695901a, so it is
fitting that I now destroy it :).
