[PATCH] tests/qtest/migration: Add a check for the availability of the "pc" machine

[Thomas Huth <thuth@redhat.com>]

The test_vcpu_dirty_limit is the only test that does not check for the
availability of the machine before starting the test, so it fails when
QEMU has been configured with --without-default-devices. Add a check for
the "pc" machine type to fix it.
