Is there an error in Makefile for arm64?

[MrQuansy]

In macos, command "uname -m" will return "arm64", and report Unsupported architecture here.

Hmm yeah, we should also allow arm64 here. macOS calls the architecture arm64, Linux calls it aarch64. The build is generally only meant to be run on Linux, but at least the two Docker based targets (make docker-image and make agent) run just fine on macOS.

With this patch

It's possible to build the agent from macOS, as long as Docker is installed. I'll wrap that into a PR in a moment.
