modules/rkt: wire up pipe_dtor to stop leaking rkt_pipe_t

On shutdown til_stream_untap_owner() will call into the pipe_dtor
hook if set.  So until now this was just (harmlessly) leaking the
rkt_pipe_t allocated by the pipe_ctor hook on the road to process
exit.

But in the interests of silencing ASAN about leaks on graceful
exit, I'm tying up these loose ends.

This dtor will also be utilized for performing a FORGET_TRACK via
Rocket once that's a thing.

While here I also got rid of the pipe_dtor return value, as it's
unused with no clear potential purpose (for now).
