Since qemu-kvm 1.1 [1] (since 1.3. in upstream QEMU [2])
'-no-kvm-pit-reinjection' has been deprecated.
Use -global kvm-pit.lost_tick_policy=discard instead.

---
v4: check for the property of the kvm-pit device instead of just the
kvm-pit device
keep the NO_KVM_PIT capability
v3: use -global instead of trying to add another -device
v2:
