While the driver isn't known without the sstable itself, we have a vector of them can can get it from the front element. This is not very generic, but fortunately all sstables here belong to the same table and, respectively, to the same storage and even prefix. The latter is also assert-checked by the sstable_directory atomic deleter code. For now S3 storage returns the same directory-based deleter, but next patch will change that.
