sweepbatcher/Store: do not provide LoopOut field

This data is not used by Batcher since commit
"sweepbatcher: load swap from loopdb, not own store".

Now sweepbatcher.Store depends only on tables sweeps and sweep_batches
and does not depend on swaps, loopout_swaps and htlc_keys, making it
easier to reuse.
