Comparing to the job defined for CAPZ in the test-infra repo there is small differences that may be causing the issue. It sounds like this block is relevant and it's missing on the gcp job.

extra_refs:
    - org: kubernetes
      repo: test-infra
      base_ref: master
      path_alias: k8s.io/test-infra

Also, the indentation for the security context is wrong. It's

securityContext:
privileged: true

when it should be

securityContext:
        privileged: true

What did you expect to happen:

The job finishes successfully and reports are shown.
