Belos: tests print using std::cout and occasionally cause PR testing to fail

Belos has tests that are printing unconditionally using std::cout. This occasionally fools PR testing into thinking a Belos test has failed because the expected success string "End Result: TEST PASSED" gets broken across lines. Here are a couple examples:

• Tpetra: Adding cmake support for making Tpetra allocate in shared space #12622 : https://trilinos-cdash.sandia.gov/index.php?project=Trilinos&filtercount=4&showfilters=1&filtercombine=and&field1=buildname&compare1=63&value1=PR-12622&field2=buildstarttime&compare2=84&value2=NOW&field3=buildname&compare3=63&value3=-openmp_&field4=testsfailed&compare4=41&value4=1

• Teuchos: remove spurious test output #12625 : https://trilinos-cdash.sandia.gov/index.php?project=Trilinos&filtercount=5&showfilters=1&filtercombine=and&field1=buildname&compare1=65&value1=PR-12625&field2=groupname&compare2=61&value2=Pull%20Request&field3=buildstarttime&compare3=84&value3=NOW&field4=buildstarttime&compare4=83&value4=NOW-48hours&field5=testsfailed&compare5=42&value5=0

Both of these were OpenMP builds, so maybe that's a contributing factor?

Closing as fixed. @hkthorn Thank you!
