Subject: [PATCH] Cirrus: Skip builds if same commit was previously built

Doing this to save on CI credits that might otherwise be spent
re-building the same commit multiple times.

Also prevents us from publishing the same git revision as multiple
Rolling release versions published days apart from one-another.

For details of these env vars and the `skip` keyword, see:
