unkin-agent b1f2fff045 Resolve subnet facts from secondary interfaces (#557)
BinaryLane edge hosts have a public primary IP, so region/environment/country/zone resolve to unknown even though their VPC NIC sits in a known subnet.

- match the primary IP first, unchanged for existing hosts
- otherwise scan interface bindings in name order, skipping lo, dum* and wg*
- add modules/libs/test/subnet_facts_check.rb (`ruby modules/libs/test/subnet_facts_check.rb`)
