varLib_test: test building (pseudo) VF with only a single master

Browse Source 
The SingleMaster.designspace contains only one source master, so there is no real
variation data.
Still, and empty HVAR table is added (with RegionAxisCount == fvar.AxisCount).
The gvar and cvar table are not added in this case, since they are empty and
not required.
