[PATCH] tests: fix output message formatting for crypto benchmarks

["Daniel P. Berrangé" <berrange@redhat.com>]

The output was changed from g_print to g_test_message in

    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.
