[tor-relays] Become a Fallback Directory Mirror

Every month. Rofltor03 is capped at ~10TB of incoming traffic. I can
probably spare another 5TB, but I don't think this will change things much.

Alright. I will then just leave it running, as is. You can use my other
relays as fallbacks tho.

Best regards,
Matthias
