Enables the Fake QEMU support, used mainly for testing - to run vdsm on virtual machines that do not have VT/AMD-V extensions.

This requires a setting in /etc/vdsm/vdsm.conf

  fake_kvm_support = True

ovirt-host-deploy should be told not to overwrite this setting. See ovirt-host-deploy README on how to do that.

No requirement for a custom property
