Increases TEST_CONN_FD_INIT to make tests working on GitHub Actions

With the current value, which is 50; it will cause some tests to fail on GitHub Actions:

  [e2e_rend_circuit_setup_legacy FAILED]

The reason is because of a process running in GitHub Actions doing something that caused a lot of file descriptors to open. So, when Tor is trying to close a fake socket it ends up closing a real one that was opened by GitHub Actions.

I already tried with 100 and it does not work. So I tried 200 and it works.
