Makefile: run golangci-lint for all supported OSes

Amend golangci-lint target to also run linters on all supported OSes
in addition to a native run.

Use CGO_ENABLED=0 because Makefile sets CGO_ENABLED=1, and
cross-compilation tools are probably not available.

Use GOARCH=arm64 for darwin because since commit f87cefc Mac builds are
arm64-only.
