chore: drop rlm_max_turns from RLM harness config (#1511)

Companion to the rlm-harness change that removes the max_turns turn cap.
The harness no longer reads RLM_MAX_TURNS, so stop setting it: remove the
RLM_DEFAULT_MAX_TURNS constant, the rlm_max_turns config field, and the
RLM_MAX_TURNS program env var.
