busybox: add backported patch to support iproute 'scope'
This is needed for avahi-autoipd, which attempts to create a link-scope route as part of its work. Without iproute scope support in busybox, the route is not created due to an error message, and hence we aren't accessible by, and can't access ourselves, IP addresses outside the link-local scope (169.254.0.0/16) unless we also have a proper non link-local IP address, which somehow defeats the purpose of zeroconf.
