[PATCH] qtests: avoid printing comments before g_test_init()

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

The TAP protocol version line must be the first thing printed on
stdout. The migration test failed that requirement in certain
scenarios:

  # Skipping test: Userfault not available (builtdtime)
  TAP version 13
  # random seed: R02Sc120c807f11053eb90bfea845ba1e368
  1..32
  # Start of x86_64 tests
  # Start of migration tests
  ....

The TAP version is printed by g_test_init(), so we need to make
sure that any methods which print are run after that.
