tiff: set status for CVEs firx in 4.7.0

NDV DB tracks these CVEs as version-less.
So these re-appered in CVE reports after patch files were removed during
last upgrade although the CVEs are fixed.
This seems to be a current trend with RedHat CVEs since due due to
current NVD CVE annotation situation, version-less CVEs are no longer
getting fixed-in added version when available.
