Fix SCE finding XPath to allow nesting with OCILs

[cipherboy]

Description:

When building data streams with complex checks (SCE combined with OVAL) that also have OCIL checks, we build a nested check system like:

<complex-check operator="OR">
    <complex-check operator="<SCE-CROSS-OVAL>">
        <OVAL />
        <SCE />
    </complex-check>
    <OCIL />
</complex-check>

However, the XPath for finding such checks (to include the SCE in the data stream) required the SCE check to be a direct descendant of the rule. Modify the XPath to allow arbitrary nesting on the inner SCE.

Rationale:

Fix is broken :-)

Hi @cipherboy. Thanks for your PR.

I'm waiting for a ComplianceAsCode 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.
