odhcp6c: add route-workaround for broken IPv6-ISPs
Some ISP seem to only do stateful DHCPv6 and not sending RAs.
This is technically broken because plain DHCPv6 doesn't carry routes.
We work around here by faking a default route to the DHCPv6 server
if we do not receive a useful RA from the ISP.
This workaround can be turned off with: option fakeroutes 0
