The CPU contains the updated microcode for CVE-2017-5715.

The *-guest.xml and *-json.xml CPU definitions use Skylake-Client CPU
model rather than Broadwell. This is similar to Xeon-E5-2650-v4 and it
is caused by our CPU model selection code when no model matches the CPU
signature (family + model). We'd need to maintain a complete list of CPU
signatures for our CPU models to fix this.

The original test didn't use family/model numbers to make better
decisions about the CPU model and thus mis-detected the model in the two
cases which are modified in this commit. The detected CPU models now
match those obtained from raw CPUID data.

While "x86" is a CPU sub driver name, it is not a recognized name of any
architecture known to libvirt. Let's use "x86_64" prefix which can be
used with virArch APIs.

The CPU model was implemented in QEMU by commit f6f949e929.

The change to i7-5600U is wrong since it's a 5th generation CPU, i.e.,
Broadwell rather than Skylake, but that's just the result of our CPU
detection code (which is fixed by the following commit).

As a side effect this changes the order of CPU features in XMLs
generated by libvirt, but that's not a big deal since the order there is
insignificant.
