Add pluggable transports to Tor's chutney CI job

We added PT support to chutney in #29024 (moved), now we need to make sure tor changes don't break PTs.

We should probably get chutney CI merged into Tor first, see #29280 (moved).

We need to do #30886 (moved) (test-network.sh), then #30884 (moved) (chutney CI), then this ticket (tor CI).
