board: enable ip_nonlocal_bind for IPv4 and IPv6

Browse Source 
Services could not bind to addresses not yet present on an interface,
e.g. floating VIPs managed by a routing daemon, since nonlocal bind
was left at the kernel default of disabled.

Enable net.ipv4.ip_nonlocal_bind and net.ipv6.ip_nonlocal_bind among
the router defaults in /etc/sysctl.d.

Closes #1022
