qemux86-64: re-enable paravirt guest, bring it in sync with qemux86
Seems wrong that qemux86 has this enabled and qemux86-64 doesn't.
Also this will allow people to use kvm with -cpu=host.
Right now, runqemu qemux86-64 kvm uses -cpu=kvm64 because without this
feature you can't use cpu=host on newer host kernels (>= 3.8).
This basically reverts poky

The reason of that commit (which is more than a year old) was that on
the AB running old kernels (2.6.37) we would see occasional shutdown failures.
(but if memory serves me right the fix might have been just a coincidence).
I've tested this change with by:
- run tests on runqemu qemux86-64 (without kvm) (300 seconds)
- run tests on runqemu qemux86-64 kvm (which uses by default cpu=kvm64) - (tests
took 20 seconds)
- run tests on runqemu qemux86-64 kvm with cpu=host - (tests took 18 seconds)
