libqos: extend feature bits to 64-bit
In VIRTIO 1.0 feature bits changed from 32-bit to 64-bit. (In fact, the
transports allow even more feature bits but nothing uses more than 64
bits today.)
Add 64-bit feature bit support to virtio-mmio and virtio-pci. This will
be necessary for VIRTIO 1.0 support.
