Benny Halevy 33f579f783 distributed_loader: distributed_loader::get_sstables_from_upload_dir: do not copy vector containing foreign shared sstables ...

lw_shared_ptr must not be copied on a foreign shard.
Copying the vector on shard 0 tries increases the reference count of
lw_shared_ptr<sstable> elements that were created on other shards,
as seen in https://github.com/scylladb/scylla/issues/9278.

Fixes #9278
