[PATCH] keyctl.2: SYNOPSIS: Fix prototype parameter types

[Alejandro Colomar <alx.manpages@gmail.com>]

The Linux kernel uses 'unsigned long'.
There's no reason to use the typedef '__kernel_ulong_t'.

......

$ syscall='keyctl';
$ find linux/ -type f -name '*.c' \
  |xargs pcregrep -Mn "(?s)^[\w_]*SYSCALL_DEFINE.\(${syscall},.*?\)";
linux/security/keys/keyctl.c:1869:
SYSCALL_DEFINE5(keyctl, int, option, unsigned long, arg2, unsigned long, arg3,
		unsigned long, arg4, unsigned long, arg5)
linux/security/keys/compat.c:17:
COMPAT_SYSCALL_DEFINE5(keyctl, u32, option,
		       u32, arg2, u32, arg3, u32, arg4, u32, arg5)
