Triage radare2 for Wheezy.

CVE-2018-8808 most like does not affect Wheezy, the code is different but I
cannot verify it at the moment hence I am going to mark it as no-dsa for now.

CVE-2018-8809: very similar to CVE-2018-8808. Code is quite different.

CVE-2018-8810: not-affected, vulnerable code is not present.
