Replace utils.LinkByNameOrAlias with netlink.LinkByName

[steiler]

The netlink library now supports AltNames/Aliases so we use that feature.

[steiler]

The netlink library has an issue with querying altnames that exceed the 15 char length.
Refere to: vishvananda/netlink#955
This is blocking us from completing this. Hence we need to wait for a fix.

This is sweet! Bonus points for making it into netlink 💪
