Improve how gosec G115 findings are addressed

[SaschaSchwarze0]

Changes

Gosec recently introduced the G115 rule for integer overflows. Making related changes:

• in pkg/pod/status.go, this commit simply added an exclusion where I think changing the type conversion is more reasonable. nosec is still required due to the lacking intelligence of gosec to recognize that this conversion is fine (or Go lacking parse functions for each bit size instead of one that at the end still always returns int64 ;-) ).
• in pkg/spire/controller.go, I am still getting findings. We have to run gosec directly while Tekton runs it through golangcilint. I was not able to figure out where in Tekton's golangcilint config they would be exluded, so I fixed them

Release Notes

Hi @SaschaSchwarze0. Thanks for your PR.

I'm waiting for a tektoncd 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.
