[Buildroot] [git commit branch/2021.02.x] package/putty: Ignore CVE-2021-33500

commit: https://git.buildroot.net/buildroot/commit/?id=01063c4291a7300285ad9ec044b94968dd6c2d09
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

Since putty is only affected by this CVE on Windows, ignore it in the
stable branch.  Branch master is not affected anymore already, due to
newer version which got fixed.
