reconfigure: Don't call build-derivations for upgrade-services test

This commit adjusts the upgrade-services system test to not build anything
when computing the derivation for the system test.  I came across this when
looking at issues computing the system test derivations to store in the Guix
Data Service.

* gnu/tests/reconfigure.scm (run-upgrade-services-test): Remove the use of,
and definition for ensure-service-file.
