prow.sh: fix installing Go for Kubernetes 1.19.0

Kubernetes 1.19.0 uses Go 1.15, but refers to it as 1.15.0. This broke both the check whether we need to install 1.15 (because "go version" reports 1.15, which didn't match 1.15.0) and then downloading the release archive (because the URL also only uses 1.15).
