gnu: Refactor boot-service-type and activation-service-type.

* gnu/services.scm (boot-service-type) <compose>: Use the "identity"
  procedure instead of the "append" procedure because it more accurately
  reflects the intent, which is to simply return the single list of
  extensions to which fold-services applies the "compose" procedure.
  (activation-service-type) <compose>: Likewise.
