fix(pkg): the gap-filling pass takes a candidate, not the list

find_in_store returns every candidate since this version, and its second
caller still treated the result as one path. A Lua table is truthy, so
that pass would have written a symlink named after the table's address
for every soname the host cannot resolve at all. There is no host copy to
compare against there, so coverage cannot decide; the newest candidate is
the only answer available.
