Skip non-management Packet IP addresses (#48168)

Non-management (elastic) IP addresses require manual configuration on
the host as described in https://help.packet.net/article/54-elastic-ips.
Skip those so that only the automatically configured management
addresses are used. Otherwise, a non-routable address may be returned in
the inventory.
