Work around golangci-lint issues

The version on goreleaser is broken and different from the one in
Github: golangci/golangci-lint#575 – use the direct Github URL as a
workaround.

Additionally, the installer script attempts to `install -d /go/bin` on
CircleCI, which doesn't work due to permissions. Patch that line out –
we don't need it because we make sure the directory exists anyway.
