install.goreleaser.com integration broken

Just a heads up. The removal the of the goreleaser.yaml in this commit https://github.com/tj/node-prune/commit/330b83e1fc4963b28206894403abcd3d604b84a3 broke the CI build over at https://travis-ci.org/github/goreleaser/godownloader/jobs/687930154

To fix the build over there I've submitted a PR to remove node-prune from the goreleaser repo: https://github.com/goreleaser/godownloader/pull/176
