This allows the 'delete-duplicates' call in 'differing-files' to have
the intended effect.
Before that, a "guix challenge" invocation with three builds of a store

1 store items were analyzed:
- 0 (0.0%) were identical
- 1 (100.0%) differed
- 0 (0.0%) were inconclusive

Letting GNU Tar recursively walk the complete files hierarchy side-steps the
risks associated with providing a list of file names:
