CLOUDSTACK-6241: Fix default route for IPv6 network when IPv4 not used
(cherry picked from commit e406adc0810b22ded0964080946f019be1337b52)
> Dnsmasq programming error when deploy IPv6 and IPv4 in one VM with IPv4 as

> Components: Virtual Router

> If one VM is created with both IPv4 and IPv6 network, and use IPv4 network as
> default network, then the programming of IPv6 network would be wrong in the
> VR.
> Deploying Vm with a multiple NIC's when mixing IPv4/IPv6 networks results in
> incorrect entries
> in /etc/dhcphosts.txt on VR's. As a consequence dnsmasq doesn't provide IPv6
> addresses in that case.
> Below is a content of /etc/dhcphosts.txt on one of the VR's after spinning 2
> VM's. First one had a 3 NIC's -
> one of them IPv4. Second 2 NIC's - only IPv6. As You can see first entry in
> incorrectly formatted.

> Create 3 shared networks - one ipv4 only and two ipv6 only
> Deploy VM with two NIC's in two ipv6 networks above
> Observe, that everything works as expected
> Deploy VM with 3 NIC's in all of the above defined networks, first NIC in ipv4
> network
> Observe that NIC's in ipv6 networks didn't get IP@ assigned,
> content of dhcphosts.txt on VR's serving ipv6 networks is incorrect.
