Enable CGO and CGO_DEBUG

[jianzhangbjz]

Description of the change:
When using Kuryr SDN, Kuryr forces Pods to use TCP for DNS resolution.
There is a problem for Pods running Go applications compiled with the CGO_DEBUG flag disabled. So, I just enable it. See bug for details: https://bugzilla.redhat.com/show_bug.cgi?id=1786217

Motivation for the change:
The OLM can run well in the OCP with Kuryr enabled.

Hi @jianzhangbjz. Thanks for your PR.

I'm waiting for a operator-framework 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/test-infra repository.
