gnetworkmonitornetlink: filter out IPv6 LL MC changes

Browse Source 
For some reason, IPv6 link-local multicast routing changes all the
time. GNetworkMonitorBase was already ignoring them for purposes of
emitting network-changed, but GNetworkMonitorNetlink would still
trigger a re-dump after getting one, so network-changed would end up
getting emitted anyway.
