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).
