[RFC QEMU PATCH 16/18] virtio-gpu: fix hw-display-virtio-gpu.so undefined symbol virtio_gpu_virgl_resource_unmap

[Huang Rui <ray.huang@xxxxxxx>]

From: Honglei Huang <honglei1.huang@xxxxxxx>

Move virtio_gpu_virgl_resource_unmap to virtio-gpu.c cause virtio-gpu.so
call this function but this function in virtio-gpu-gl.so before.

Add virgl dependency  into virtio-gpu-gl.so.
