virtio-gpu: allocate shareable 2d resources on !win32

Browse source 
Similar to what was done in commit 9462ff46 ("virtio-gpu/win32: allocate
shareable 2d resources/images") for win32, allocate resource memory with
memfd, so the associated display surface memory can be shared with a
different process.
