bug#33368: "guix archive" fails because of guix-authenticate

With the strace log (see below) that's pretty obvious: the daemon
doesn't find the guix-authenticate binary. But where should it be, and
why is it missing on my machine?

> Is the guix-daemon also recent?

A bit less than the rest of guix, but I did update it after the Great
Pull Revolution. The first line of the strace log contains the path in
the store, which should say all there is to know about my daemon.

Cheers,
  Konrad.
