odhcp6c: add workaround for broken extendprefix scenario
...
Extendprefix is typically used to extend an IPv6 RA prefix from a mobile
wan link to the LAN; such scenario requires correct RA prefix settings
like the on link flag not being set.
However some mobile manufacter set the RA prefix on link flag which breaks
basic IPv6 routing.
Work around this issue by filtering out the route being equal to the
extended prefix.

odhcp6c : Silence mtu write error warnings
...
Silence warning "daemon.notice netifd: wan6 (1139): sh: write error: Invalid argument"
when an invalid MTU is received via RA as kernel refuses to accept IPv6 mtu values
which are smaller than 1280 and bigger than the device mtu.

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
