modules/rkt: use helper for pipe track names

This eliminates the ad-hoc track_name[] allocation and
construction, since the track_name wasn't being used after
getting the track anyways.  No point wasting the memory on it,
and the little helper constructing the name on-stack exists now
for another future use @ rkt_create_context().
