cpu: Move feature expansion out of cpuBaseline

Browse Source 
cpuBaseline is responsible for computing a baseline CPU while feature
expansion is done by virCPUExpandFeatures. The cpuBaselineXML wrapper
(used by hypervisor drivers to implement virConnectBaselineCPU API)
calls cpuBaseline followed by virCPUExpandFeatures if requested by
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES flag.

The features in the three changed test files had to be sorted using
"sort -k 3" because virCPUExpandFeatures returns a sorted list of
features.
