hack: move debian priority ignore to account for legacy records (#624)

#622 added some additional cves to
ignore the debian provided priority; however, most of the applied to
records from debian 10 which are now captured in the legacy storage and
don't follow the normal processing, so this relocates the logic to a
place which will also process loegacy entries.
