include/linux/syscalls.h: use pid_t instead of int

In include/linux/syscalls.h, the four functions sys_kill, sys_tgkill,
sys_tkill and sys_rt_sigqueueinfo are declared with "int pid" and "int
tgid".

However, in kernel/signal.c, the corresponding definitions use the more
appropriate "pid_t" (which is a typedef'd int).

This patch changes "int" to "pid_t" in the declarations of sys_kill,
sys_tgkill, sys_tkill and sys_rt_sigqueueinfo in <linux/syscalls.h> in
order to harmonize the function declarations with their respective
definitions.
