unbound: fix crash when using odhcpd w/o dnsmasq

When using the configuration under "Unbound and odhcpd" in the package's
README.md, the scripts generated a malformed config file for unbound, due
to an "ip route" command giving extra output lines with the string
"anycast" where the awk script expects an address. These are now filtered.
