[NETNS][IPV6] fib6 rule - dynamic allocation of the rules struct ops
The fib6_rules_ops structure is dynamically allocated, so that allows
to make several instances of it per network namespace.
The global static fib6_rules_ops structure is renamed to
fib6_rules_ops_template in order to quickly memcopy it for the
structure initialization.
