Disable lock contention logging in checkqueue_tests

as some of these tests are designed to be heavily contested to trigger race
conditions or other issues. This created very large log files when run with
DEBUG_LOCKCONTENTION defined (up to v22) or with lock logging enabled by default
in current master.

Examples running the following command:

./src/test/test_bitcoin -t checkqueue_tests/test_CheckQueue_Correct_Random -- DEBUG_LOG_OUT > testlog.txt
