Refactor fib4/fib6 functions.

No functional changes.

* Make lookup path of fib<4|6>_lookup_debugnet() separate functions
 (fib<46>_lookup_rt()). These will be used in the control plane code
 requiring unlocked radix operations and actual prefix pointer.
* Make lookup part of fib<4|6>_check_urpf() separate functions.
 This change simplifies the switch to alternative lookup implementations,
 which helps algorithmic lookups introduction.
* While here, use static initializers for IPv4/IPv6 keys
