The output was changed from g_print to g_test_message in
commit 24441f912e
Author: Marc-André Lureau <marcandre.lureau@redhat.com>

tests: do not print benchmark output to stdout
As this makes the TAP output invalid. Use g_test_message().
The functions do not result in equivalent output. The g_print
statements were putting all the information on a single line
for ease of interpretation. The change to g_test_message split
the output across many lines making it painful to read.
The opportunity is used to tweak the information printed to be
more consistent across tests.
