lib: add vrf-lite bind capability to vrf APIs

Because socket creation is tightly linked with socket binding for vrf
lite, the proposal is made to extend socket creation APIs and to create
a new API called vrf_bind that applies to vrf lite. The passed interface
name is the interface that will be bound to the socket passed.
