router(*): Use unicast rather than multicast

Browse source 
Due to an unfathomable issue where I would need to recompile with full debug keepalived,
keepalived seems to be not seeing the multicast packets on the vrrp-router
and thus we need to fallback to the disgusting unicast solution.

Well, let's move on.
