5c40e7b test: allows test_runner command line to receive parameters for each test (marcoagner)

Pull request description:

  Fixes bitcoin#14791.
  Seems to address the asked behaviour in a simple way, but could address more if a more complex behaviour is found to be needed (e.g. call `rpc_bind --ipv4` without the ".py" and have it added).
