Don't perform extra go env calls in go/packages. Load only needed go env vars in golangci-lint. Stay in sync by enabled analyzers in go vet: remove nilness and atomicalign analyzers, add errorsas analyzer. Don't build SSA for govet. Standalone govet runs 25% faster than before. All runs can be 5-10% faster than before. Relates: #208
