Convert netdev.c to produce KTAP output with 3 tests:
- dev_dump: dump all netdev devices, skip if empty
- dev_get: query first device from dump by ifindex
- ntf_check: subscribe to "mgmt", create a veth via rt-link,
verify netdev notification is received, then delete the veth
Remove stdin/scanf-based UI. Add rt-link dependency for the veth
notification test.
