hw/i386/vmport: Report vmware-vmx-type in CMD_GETVERSION
As can be seen from VmCheck_GetVersion() in open-vm-tools code,
CMD_GETVERSION should return vmware-vmx-type in ECX register.
Default is to fake host as VMware ESX server. But user can control
this value by "-global vmport.vmware-vmx-type=X".
