Subject: [PATCH] qemu: Use virtio network device for aarch64/virt

This patch changes network device type used by default from rtl8139
to virtio when architecture type is aarch64 and machine type is virt.
Qemu doesn't support any other machine types for aarch64 right now and
we can't make any other aarch64-specific tuning in this function yet.
