hw/display: Restrict virtio-gpu-udmabuf stubs to !Linux
When using qemu configured with --enabled-modules, the generic stubs are used instead of the module symbols: qemu-system-x86_64: -device virtio-vga,blob=on: cannot enable blob resources without udmabuf Restrict the stubs to Linux and only link them when CONFIG_VIRTIO_GPU is disabled (only the modularized version is available when it is enabled).
