Revert rbac addition for BuildRun resource

[TomerNewman]

Because we will not use Shipwright, We should revert kmm to not have RBAC for Shipwrights resources like BuildRun.
This commit reverts to the old RBAC configuration.

Hi @TomerNewman. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
