Version 2 and 3 of the library should have different symbol names

[PierreF]

Describe the bug

Same issue as #1136 but for other symbol.
I've the issue with open_smc, close_smc and get_temperature

To Reproduce

package main

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

func main() {}

with go.mod:

module example.com

go 1.17

require (
        github.com/shirou/gopsutil v3.21.10+incompatible
        github.com/shirou/gopsutil/v3 v3.21.10
)

require (
        github.com/StackExchange/wmi v1.2.1 // indirect
        github.com/go-ole/go-ole v1.2.6 // indirect
        github.com/lufia/plan9stats v0.0.0-20211012122336-39d0f177ccd0 // indirect
        github.com/tklauser/go-sysconf v0.3.9 // indirect
        github.com/tklauser/numcpus v0.3.0 // indirect
        golang.org/x/sys v0.0.0-20211013075003-97ac67df715c // indirect
)

Then build (go mod tidy may be required before):

go build
[...]

Expected behavior

The program should build correctly.

Environment (please complete the following information):

• Mac OS: [paste the result of sw_vers and uname -a

% sw_vers
ProductName:	macOS
ProductVersion:	12.0.1
BuildVersion:	21A559

% uname -a
Darwin hostname.local 21.1.0 Darwin Kernel Version 21.1.0: Wed Oct 13 17:33:01 PDT 2021; root:xnu-8019.41.5~1/RELEASE_ARM64_T6000 arm64

% go version
go version go1.17.2 darwin/arm64

Additional context

Note that this conflict is not necessary limited to version 2 and version 3 of gopsutil. If any other package define the same C function (e.g. version 2 of gopsutil and github.com/lufia/iostat, which both define readdrivestat) a conflict also occur :(

For this reason, we might need to prefix the function no only with "v3" but some unique enough prefix. "gopsutil_v3_" ?
