Subject: [PATCH] ci: drop mpool_select_killer regression step

The step guarded against MpoolSelect panics from non-total sort
comparators and gas-limit underflow. Both are fixed, and comparator
total order is covered by unit tests, while the step cost ~6 minutes
of the 30-minute calibnet check budget.
