test: Use puts for inferred clock gator borrow failures

The inferred_clock_gator_time_borrow and inferred_clock_gator_time_borrow_covered regressions moved from PASSFAIL_TESTS to .ok golden comparison, so a thrown utl::error is no longer required to flag a failure.

Replace the utl::error calls with puts, keeping the same message text. On failure the message is now emitted to stdout and caught by the golden .ok diff; the passing golden output is unchanged because these branches only fire when the borrow check fails.
