tests/unit/test-smp-parse: Test smp_props.has_clusters

Browse Source 
The smp_props.has_clusters in MachineClass is not a user configured
field, and it indicates if user specifies "clusters" in -smp.

After -smp parsing, other module could aware if the cluster level
is configured by user. This is used when the machine has only 1 cluster
since there's only 1 cluster by default.

Add the check to cover this field.
