ManualOwnership: don't diagnose unknown callees

[kavon]

Since the annotation is non-viral, we don't want to emit an error when we counter a callee that is unknown.

Didn't mean to remove code owners as reviewers. Github's UI didn't update when I opened the PR.

@swift-ci smoke test

preset=buildbot,tools=RA,stdlib=DA
@swift-ci Please test with preset macOS Platform

@swift-ci smoke test windows

Hmm, there's another diagnostics difference in this preset configuration than expected:

For now I'm going to merge this fix. It may not completely unblock that CI job, but it does fix the original issue.
