Remove prow-build service account from group, grant permissions directly #1401

Followup to #1393. Looks like I was wrong about service accounts picking up permission from group membership (ref: #1393 (comment))

Instead of granting all permissions that k8s-infra-staging-ci-images@ has, grant only write access to gcr.io/k8s-staging-ci-images

This replicates what I did manually

gsutil iam ch serviceAccount:prow-build@k8s-infra-prow-build.iam.gserviceaccount.com:roles/storage.objectAdmin gs://artifacts.k8s-staging-ci-images.appspot.com
gsutil iam ch serviceAccount:prow-build@k8s-infra-prow-build.iam.gserviceaccount.com:roles/storage.legacyBucketWriter gs://artifacts.k8s-staging-ci-images.appspot.com

Instead of granting all permissions that k8s-infra-staging-ci-images@
has, grant only write access to gcr.io/k8s-staging-ci-images
