Fix prometheus tests failing after bootstrap img bump on CI (#2113)

For some reason curling localhost stopped working for us after https://github.com/kubevirt/project-infra/pull/1616,
So let's change to 127.0.0.1. Does not reproduce using on my machine when using a prow mimic:
https://github.com/kubernetes/test-infra under `prow/cmd/phaino`.
Only reproduces on the real prow env. thanks dhiller.
