lib: add usual func to install SRv6 localsid (step4)

Browse source 
This commit add usuful function to configure SRv6 localsid
which is represented with seg6local lwt route.
Now, it can support only NEXTHOP_TYPE_IFINDEX route.
Actual configurationof SRv6 localsid is performed with
ZEBRA_ROUTE_ADD. So this is just a wrapper function
for route-install.
