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.
