Upgrade gopsutil for Apple silicon mac compatibility of go test

[hiroshi]

from #295 (comment)

This will fix Apple silicon mac imcompatibility issue of go test.

---

• Tests passed.
• Fix conflicts with target branch.
• Update jira ticket description if needed.
• Attach screenshots/console output to confirm new behavior to jira ticket, if applicable.

When all checks have passed and code is ready for the review, bot should add pmm-review-exporters team as the reviewer. That would assign people from the review team automatically. Report any issues on our Forums and Discord.

The test was started after this change, but it failed by another problem. I'm not sure what's wrong with it.
