updated dockerfiles for grpc builds for powerPC compilation~ #2262

I'm still wondering if we should not support ppc64le based on this discussion: https://github.com/kubeflow/katib/pull/2262#pullrequestreview-1934843268

Anyway, we should resolve that discussion before we move this forward.

@tenzen-y please refer to https://github.com/kubeflow/katib/pull/2262#issuecomment-1998212429 - does that help? As mentioned, we are happy to help maintaining, especially if anything architecture-specific comes up...
