Signed-off-by: JmPotato ghzpotato@gmail.com

What problem does this PR solve?

Try to run make tools/bin/golangci-lint on M1 macOS.

It will fail.

What is changed and how it works?

To make sure the M1 (or go 1.16) is supported, I upgrade the golangci-lint to the latest version. See golangci/golangci-lint#1725 for more details.
