Makefile: replace the Go linter and apply all their recommendations

Previously, we use golangci-lint as linter.
This linter does not provides any useful recommendation lately and the
development is quite a mess, sometimes its break when using Go tip.

In this changes we replace it with revive, fieldalignment, and shadow;
and fix all of their recommendations.
