signalprocessor: don't set channel positions in template-caps, Fixes #601775

Browse source 
Revert the changes that added audio positions to template caps. We have an un-
fortunate limitation in core that does not allow to do it. Keep a few things
commented out, so that the channel position can later on be set in setcaps.
