The test-vmstate test is a bit chatty because it triggers various
expected failure scenarios and the code in question uses error_report
instead of accepting 'Error **errp' parameters. To silence this test the
stubs for error_vprintf() were changed to send errors via
g_test_message() instead of stderr:

tests: send error_report to test log
Implement error_vprintf to send the output of error_report to
the test log. This silences test-vmstate.

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints
Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:
and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.
This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.
