[PATCH] go-bin for macOS on Apple Silicon

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

The Go team has released Go 1.16 beta 1 with a binary release for 
darwin/arm64. I tried adding it to go-bin, but I am not sure if I am doing 
it right. I left the other architectures at 1.14.2 as before and override 
PKGNAME on darwin/arm64.

What's more, I have no ARM Mac to test this. I would be grateful if 
someone could try it on theirs.

Any comments? It would be awesome if we could get this in before the 
branch.
