services: herd: "Resolve" transient services only when needed.
This allows us to get rid of the "eval root" actions, which in turn would lead to confusing "Evaluating user expression" messages. Fixes <https://issues.guix.gnu.org/55857>. * gnu/services/herd.scm (resolve-transients): In 'values', avoid 'eval-there' call when UNRESOLVED is empty.
