daemon: optimizePath: Detect some .links corruptions.
If automatic store optimisation is enabled, and a hard-linked file in the store gets corrupted, then the corresponding .links entry will also be corrupted. In that case, trying to repair with --repair or --repair-path won't work, because the new "good" file will be replaced by a hard link to the corrupted file. We can catch most of these cases by doing a sanity-check on the file sizes.
