services: guix-build-coordinator: Fix service activation parts.

Don't hardcode usernames, as these are in the config. Also fix the %user being
missing from the queue-builds service activation.

* gnu/services/guix.scm (guix-build-coordinator-activation,
guix-build-coordinator-agent-activation): Use config for the user name.
(guix-build-coordinator-queue-builds-activation): Define %user.
