Pass `enable_transports` in `daemon` fixture

Forward the `tpt_proto` fixture val into spawned daemon
subprocesses via `run_daemon(enable_transports=..)` and
sync `_runtime_vars['_enable_tpts']` in the `tpt_proto`
fixture so sub-actors inherit the transport setting.

Deats,
- add `enable_transports={enable_tpts}` to the daemon
  spawn-cmd template in `tests/conftest.py`.
- set `_state._runtime_vars['_enable_tpts']` in the
  `tpt_proto` fixture in `_testing/pytest.py`.
