Route the --clone-all copytree ignore through _non_exportable_entries so a
live source profile holding a gateway or agent-browser socket (or a FIFO)
no longer aborts the clone with [Errno 6] No such device or address.
.pyc/.pyo and the root exclude sets keep their existing handling.
hermes_cli/profile_distribution.py:_copy_dist_payload is left alone: it
copies from a freshly extracted distribution archive (a staged temp tree),
never from a live profile, so it cannot meet a socket.
Extends test_clone_all_does_not_copy_cron_jobs to cover the clone path.
