Use netlink for link state queries

Rather than do a once-off query for interfaces at boot, we should be
using netlink to query for initial link states, and listen for link
update & deletion events.

This change adds functionality to receive RTM_NEWLINK and RTM_DELLINK
messages, and updates the interfaces array using that.
