[PATCH v2 7/7] tests/fw_cfg: Run the tests on big-endian targets

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

We have been restricting our fw_cfg tests to the PC machine,
which is a little-endian architecture.
The fw_cfg device is also used on the SPARC and PowerPC
architectures, which can run in big-endian configuration.

Since we want to be sure our device does not regress
regardless the endianess used, enable this test one
these targets.

The NUMA selector is X86 specific, restrict it to this arch.
