[OE-core] [PATCH] cve-check: remove redundant readline CVE whitelisting

[Ross Burton]

CVE-2014-2524 is a readline CVE that was fixed in 6.3patch3 onwards, but the
tooling wasn't able to detect this version.  As we now ship readline 8 we don't
need to manually whitelist it, and if we did then the whitelisting should be in
the readline recipe.
