contrib/vhost-user-gpu: add support for sending dmabuf modifiers
virglrenderer recently added virgl_renderer_resource_get_info_ext as a
new api, which gets resource information, including dmabuf modifiers.
We have to support dmabuf modifiers since the driver may choose to
allocate buffers with these modifiers for efficiency, and importing
buffers without modifiers information may result in completely broken
rendering.
