Merge bitcoin/bitcoin#33698: test: Use same rpc timeout for authproxy and cli

66667d6512 test: Use same rpc timeout for authproxy and cli (MarcoFalke)

Pull request description:

  It seems odd to use different timeouts (and timeout factors) depending on whether the Python RPC proxy is used, or the bitcoin rpc command line interface.

  Fix it by using the same timeout.

  This can be tested by introducing a timeout error and checking it happens with and without `--usecli` after the exact same time.

  Example timeout error:

  ```diff
  diff --git a/test/functional/mining_template_verification.py b/test/functional/mining_template_verification.py
