What did you do?

I want to get information from unix.Uname() - this works fine, however the fact that Utsname has all members as int8 is making working with the result a bit cumbersome. It would be simpler if this would be a [65]byte instead because than the bytes package can be used on it. Unless I miss something the only ways to convert this are:

package main

import (
	"bytes"
	"golang.org/x/sys/unix"
	"unsafe"
)

func main() {
	var utsname unix.Utsname
	unix.Uname(&utsname)

	// convert using unsafe.Pointer()
        p := (*[len(utsname.Machine)]byte)(unsafe.Pointer(&utsname.Machine))
	println(string(p[:]))
	
	// iterate and convert
	buf := make([]byte, 0, len(utsname.Machine))
	for _, i := range utsname.Machine {
		buf = append(buf, byte(i))
	}
	println(string(buf))
}

What did you expect to see?

Ideally a simple println(string(utsname.Machine[:])) would be enough to convert it to a string without the need for the unsafe.Pointer() casting.

I am happy to work on a PR if there is a chance for this to get accepted.
