    routing: restore opt_route.h in route.c, fib_algo teardown was compiled out
    
    Removal of opt_route.h left route.c without FIB_ALGO, skipping
    fib_destroy_rib() in rt_table_destroy(). Explicitly guard it to clean up
    fib_algo instances and callouts before releasing the rib_lock rmlock,
    preventing a page fault in softclock and VNET resource leaks.
