This enables support for nested SVM using the regular CPU
model/features block. If the CPU model or features include
'svm' or 'vmx', then the '-enable-nesting' flag will be
added to the QEMU command line. Several of the models
already include svm support, but QEMU was just masking out
the svm bit silently. So this will enable SVM on such
models
ACK to this patch, but...

...as a followup, should we add to tests/qemuhelpdata an example of qemu
