test: cunit: tm fix tm execution under CI

Some test like this can fail under not clear environment.
Make CI env detection more general with implementing helper
function.

  Test: traffic_mngr_test_shaper ...
 traffic_mngr.c:2531:test_shaper_bw():min=0 avg_rcv_gap=180
		max=249 std_dev_gap=109
traffic_mngr.c:2534:test_shaper_bw():  expected_rcv_gap=250
		acceptable rcv_gap range=198..314
FAILED
    1. traffic_mngr.c:2549  - (min_rcv_gap <= avg_rcv_gap)
		&& (avg_rcv_gap <= max_rcv_gap)
    2. traffic_mngr.c:3842  - test_shaper_bw("bw40",
		"node_1_1_1", 3, 40 * MBPS) == 0
  Test: traffic_mngr_test_scheduler ...passed
