Install a nightly Docker cleanup timer with init --systemd (v0.9.7)

Browse Source 
Port of the legacy host's docker-prune.timer: 02:00 host time,
Persistent=true, docker system prune -af — but without --volumes, so
the per-repository Gradle cache volumes survive. The units are
host-global; several GitTally instances share one timer.
