[host][linux]: fix utmp size on linux/arm64

[shirou]

fix: #1129

Update host_linux_arm64.go with below environment

• Raspberry Pi 4
• Linux raspberrypi 6.1.21-v8+ chore(deps): bump golangci/golangci-lint-action from 5.3.0 to 6.0.0 #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux
• go version go1.22.0 linux/arm64

Note: type file has been changed by hand

uint -> int

The cgo command output []uint in arm64. But it is []int, at least on amd64. This difference caused build to fail on arm64.

There is a technique to use generics, but I changed it by editing the arm64 definition from uint to int by hand, in order to keep backward compatibility.

added padding after type

padding is required for parse.

Tested on aarch64. It works somehow, but I'm not sure if the output is correct.

root@s1:~/go-test# cat test.go 
package main

import (
    "fmt"
    "github.com/shirou/gopsutil/v3/host"
)

func main() {
    fmt.Println(host.Users())
}

@JosefRypacek Thank you for your quick confirmation. I found a padding was missing. I added it on
cbefbb0. Sorry to bother you, but could you try again?

[JosefRypacek]

Works better now. Thanks!
