    Adjust ipfw_{init,destroy}_*() definitions to avoid clang 15 warning
    
    With clang 15, the following -Werror warnings are produced:
    
        sys/netpfil/ipfw/ip_fw_sockopt.c:187:19: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        ipfw_init_counters()
                          ^
                           void
        sys/netpfil/ipfw/ip_fw_sockopt.c:196:22: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        ipfw_destroy_counters()
                             ^
                              void
        sys/netpfil/ipfw/ip_fw_sockopt.c:3241:23: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        ipfw_init_obj_rewriter()
                              ^
                               void
        sys/netpfil/ipfw/ip_fw_sockopt.c:3249:26: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        ipfw_destroy_obj_rewriter()
                                 ^
                                  void
    
    This is because ipfw_init_counters(), ipfw_destroy_counters(),
    ipfw_init_obj_rewriter(), and ipfw_destroy_obj_rewriter() are declared
    with (void) argument lists, but defined with empty argument lists. Make
    the definitions match the declarations.

    (cherry picked from commit 62030bb8538cb3775f6259c81c2c30a533f3ab10)
