ospf6d: Fix External routes ECMP
Handle RFC 2328 16.4 Calculating AS external routes with ECMP
For ASBR route, if it is learnt via new LSA and contains
different nexthop list. First lookup route in ospf6 route table
if it exists, merge nexthop list to existing and call the callback
to install into FIB (zebra). Delete created new route as it is
identical to existing entry in route table.
Ticket:CM-16139
Testing Done:
Run two ASBR with 2 ECMP paths from each
DUT neighbor receievs 4 ECMP path to a external route.
ospf6 installs all 4 ECMP path to FIB/RIB
