Block local addresses for rendezvous on RSOS servers
Build on the work in #8976 (moved) to block local addresses for rendezvous on RSOS servers.
We'll need to add to the function:
- tor_addr_is_local
- any local interface address on the RSOS
- any configured address on the RSOS
(This is very similar to #17027 (moved), I wonder if we could re-use that code?)
