qemu: Fix up the default machine type for QMP probing

Browse Source 
The default machine type must be stored in the first element of
the caps->machineTypes array. This was done for help output
parsing but not for QMP probing.

Added a helper function qemuSetDefaultMachine to apply the same
fix up for both probing methods.

Further, it was necessary to set caps->nmachineTypes after QMP
probing.
