PR26810: debuginfod should tolerate some absence/renaming sans grooming

debuginfod now knows to handle a case where a buildid search is
satisfiable from more than one source (e.g., archive location), but
some of them are invalid.  New exception catching beneath the sqlite
scanning loop ensures all possible matches are scanned in case of
errors.
