[PATCH v2 4/7] tests/fw_cfg: Let the tests use a context

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Introduce the local QTestCtx structure, and register the tests
with qtest_add_data_func(ctx).
For now the context only contains the machine name (which is
fixed to the 'pc' machine, since this test only runs on the
x86 architecture).

v2: Use const QTestCtx *ctx, do not g_new(QTestCtx) (Laszlo)
