Subject: [PATCH] backends: jack: display playback only devices

When starting ardour using the jack backend, playback only devices
currently do not get displayed. Mixing and Mastering only workspaces
with e.g. a single USB Dac should be a common use case. Take this use
case into account by adding them to the device list. Tested on Linux
with jack-alsa.
