Add "CVE:" tag to current patches in OE-core

Add "CVE:" tag to current patches in OE-core

The currnet patches in OE-core doesn't have the "CVE:"
tag, now part of the policy of the patches.

This is patch add this tag to several patches. There might
be patches that I miss; the tag can be added in the future.
