cve-extra-exclusions.inc: add exclusion list for intractable CVE's
The preferred methods for CVE resolution are: 1. Version upgrades where possible 2. Patches where not possible 3. Database updates where version info is incorrect 4. Exclusion from checking where it is determined that the CVE does not apply to our environment In some cases none of these methods are possible. For example the CVE may be decades old with no apparent resolution, and with broken links that make further research impractical. Some CVEs are vauge with no specific action the project can take too. This patch creates a mechanism for users to remove this type of CVE from the cve-check results via an optional include file. Based on an initial patch from Steve Sakoman <steve@sakoman.com> but extended heavily by RP. (From OE-Core rev: 4a70af7b89d2ddff341b724a97cb96987874a3b0) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+# It contains all the information we are aware of about an issue and analysis about
+# why we believe it can't be fixed/handled. Additional information is welcome through
