Make the trim knob on busses show only if there is audio

Browse Source 
The trim knob has been designed to operate only on audio channels. If
the bus has none, hide the knob that would otherwise have no effect at
all.

Factor the trim control show/hide code out of MixerStrip::set_route(),
and also call that code in response to I/O changes in the route.
