Change definition of pipe_chmod() from K&R to C99, to avoid the

following clang warning:

sys/kern/sys_pipe.c:1556:10: error: promoted type 'int' of K&R function parameter is not compatible with the parameter type 'mode_t'
      (aka 'unsigned short') declared in a previous prototype [-Werror]
        mode_t mode;
               ^
sys/kern/sys_pipe.c:155:19: note: previous declaration is here
static fo_chmod_t       pipe_chmod;
                        ^
