[PATCH] splice.2: Use 'off64_t' instead of 'loff_t'

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

The kernel syscall uses 'loff_t', but the glibc wrapper uses 'off64_t'.
Let's document the wrapper prototype, as in other pages.

......

.../glibc$ grep_glibc_prototype splice
sysdeps/unix/sysv/linux/bits/fcntl-linux.h:398:
extern __ssize_t splice (int __fdin, __off64_t *__offin, int __fdout,
			 __off64_t *__offout, size_t __len,
			 unsigned int __flags);
.../glibc$
