fix(rflood): set HOME=/config and flood --auth none --rtsocket for jesec

- HOME=/config makes rtorrent read /config/.rtorrent.rc and use /config/session/
- flood --auth none disables login requirement
- flood --rtsocket points to socket path from rtorrent.rc
- rtorrentSocket value used consistently in both configmap and command args
