Merge bitcoin/bitcoin#31343: test: avoid internet traffic in rpc_net.py

988721d37a test: avoid internet traffic in rpc_net.py (Sebastian Falbesoner)

Pull request description:

  In order to avoid connecting to the internet in the functional test `rpc_net.py`, specify a non-working proxy (parameter `-proxy=127.0.0.1:1`, same approach as in #31142) for the nodes.  There is at least one known instance where this is currently happening on master where a connection attempt to a public IP is made (see also the discussion in #31339):

  17834bd197/test/functional/rpc_net.py (L253)

  Can be tested by running
  ```
  $ sudo tcpdump -i eth0 host 11.22.33.44
  ```
  both on master and the PR branch and verifying that no packets appear in the tcpdump in the latter anymore.
