This reverts commit 69f6edc1a8596d2cb4c67e0435d35633af6f3cbc. The intention is good, but nodist_systemdservice_DATA are meant to be disposable artefacts generated from corresponding ‘.in’ files. etc/guix-gc.timer doesn't fit that description, breaking builds: $ make clean && make … make[2]: *** No rule to make target 'etc/guix-gc.timer', needed by 'all-am'. Stop.
