ff7796372b seccomp: x86_64: Allow fstat for video device

to check GPU type. dri_init calls drmGetRenderDeviceNameFromFd
in libdrm which calls fstat.

57df6a0ab2 devices: virtio: Initial implementation of virtio-video device 
This CL adds a fundamental part of the virtio video device, which will
be shared between the encoder and the decoder.
Both devices uses the virtio-video protocol proposed as RFC v3 [1,2].
The corresponding driver code is at CL:2060327 and its children CLs.

The actual decoding and encoding logic will be implemented in different
CLs.
