Go: Build fails when go.mod has replace with relative URL

Building (in nix) fails when go.mod has replace with relative URL.

(Demo project properly builds out of Nix without an issue.)

The use of replace is necessary because URL does not match actual project URL which is a monorepo and private.

Thanks to @SuperSandro2000 for finding root issue:
buildGoModule is using go install which does not support replace in go.mod.

Notice:

go install github.com/superherointj/go-barquinho-demo/src@latest

Shows same error message. So the problem is actually with go install.
