Keep binaries until inspected; seeding writes binaries only for inspection

Par2 naming needs the fingerprint inspection stores on a binary, and the
GC deleted seeded binaries (6 h unfingerprinted, 48 h stale) long before
the inspection queue reached them. binaries.awaiting_inspection protects
them for up to 7 days; the GC deletes use partial indexes so they don't
read past waiting rows. Seeding no longer creates binaries for files that
aren't inspected (~85% of a.b.ath), which only churned the table.
