This was missed while introducing the tty-based serial access.
The only remaining use of wait_for_xmitr with tty-based access is in
spk_synth_is_alive_restart to check whether the synth can be restarted.
With tty-based this is up to the tty layer to cope with the buffering
etc. so we can just say yes.
