[NETNS]: Refactor fib initialization so it can handle multiple namespaces.

This patch makes the fib to be initialized as a subsystem for the
network namespaces. The code does not handle several namespaces yet,
so in case of a creation of a network namespace, the
creation/initialization will not occur.
