This introduces a PRODUCT environment variable that is used to set a constant
at dockerversion.ProductName.

That is then used to set BuildKit's ExportedProduct variable in order to show
useful error messages to users when a certain version of the product doesn't
support a BuildKit feature.

Better to have a default value? (moby? moby-engine? dockerd?)

I think it's better to keep it empty, because there are no "moby releases". Docker will set this.

Why's this commented out? Does this need a TODO?

That's in buildkit. Feel free to change it there, but I don't think it's a blocker for this PR.
