linux: net/ipv{4,6}: Enable commonly used functionality
This addresses some assumptions made by systemd about having multiple
routing table support in the kernel. systemd-networkd will try and
provision mutliple routing tables + policies and will silently break
neighbor advertisement responses due to policy configurations on a
single table.
It also adds support for SLAAC based router settings and faster
duplicate address detection.
