The recipe snapshot kept only the archives a profile or platform names,
so provenance_report --missing named no set for dumps a public romset
carries (fm7740sx holds the FM77AV40SX DICROM, EXTSUB and KANJI2 ROMs).
The importer now also keeps the sets holding a catalog entry the
collection lacks. Reimported from mame0289 and the cached FBNeo DATs:
MAME 1726 to 2148 recipes, FBNeo 104 to 111, none dropped.
