cve-exclusion: review the last of the historical kernel CVEs

Review the last of the historical kernel CVEs.  Issues which are
specific to other platforms or distributions are ignored in the kernel
recipe itself, whereas general security concerns like "ICMP leaks
information" and "USB has flaws" are ignored with more details in the
extra-exclusions file as before.
