ci: skip actions/cache on self-hosted runners (#11986)

cargo registry/target and docker-image caches are already local on a
persistent self-hosted runner; the save/restore pass is pure overhead
(the setup-go cache-save stall on awscli-tests was the same pattern).
Gate every actions/cache step on runner.environment == 'github-hosted'.
