    runqemu: Move virtio RNG to machine configuration
    
    Not all QEMU machines (outside of those available in OE-Core) are
    capable of using the virtio-rng-pci device due to various machine models
    not having a pci/virtio bus. This makes it such that the use of the
    '-device virtio-rng-pci' flag to QEMU is machine specific.
    
    This patch removes the general addition of the flag to all runqemu
    targets and adds the flag into the QB_OPT_APPEND for all the qemu*
    machines in OE-Core that support its use (which is all of them).
