Fixed IPv6 source address lookup

Because Linux kernels prior to 3.0 do not support RTA_PREFSRC for
IPv6 routes we didn't use NLM_F_DUMP to get all routes.
Still routes installed with policies are installed also for IPv6.
So since only one route is returned without DUMP, and we ignore
all routes from our own routing table, no source address was found
during roaming if DST of the installed route included the IKE peer.

With newer kernels we can now use DUMP as we did for IPv4 already,
for older kernels we do so if our own routes are installed in a
separate routing table, otherwise we still use GET.
