Some rtnetlink selftests assume the presence of ifconfig and iproute2 support for the `proto` keyword in `ip address` commands. These assumptions can cause test failures on modern systems (e.g. Debian Bookworm) where:
- ifconfig is not installed by default - The iproute2 version lacks support for address protocol
This patch improves test robustness by:
- Skipping kci_test_promote_secondaries if ifconfig is missing - Skipping do_test_address_proto if ip address help does not mention proto
These changes ensure the tests degrade gracefully by reporting SKIP instead of FAIL when prerequisites are not met, improving portability across systems.
