ctest pass criteria is too weak

[nlslatt]

Describe the bug

ctest labels segfaults as passes on Mutrino. e.g.,

291/876 Testing: vt:*/TestReduceCollection.test_reduce_op/*_proc_8
291/876 Test: vt:*/TestReduceCollection.test_reduce_op/*_proc_8
Command: "/opt/slurm/bin/mpiexec" "-n" "8" "./test_reduce_collection" "--gtest_filter=*/TestReduceCollection.test_reduce_op/*"
Directory: /home/nlslatt/vt-auto-build/with-tracing/vt/vt-build/tests
"vt:*/TestReduceCollection.test_reduce_op/*_proc_8" start time: Oct 25 13:55 MDT
Output:
----------------------------------------------------------
srun: error: nid00016: tasks 0-7: Segmentation fault
srun: Terminating job step 19287764.1226
<end of output>
Test time =   0.99 sec
----------------------------------------------------------
Test Passed.
"vt:*/TestReduceCollection.test_reduce_op/*_proc_8" end time: Oct 25 13:55 MDT
"vt:*/TestReduceCollection.test_reduce_op/*_proc_8" time elapsed: 00:00:00

To Reproduce

Run ctest suite on Mutrino and check Testing/Temporary/LastTests.log afterward for verbose output.

Expected behavior

Segfaults should be classified as test failures.
