guard buffer export API if not available

Browse source 
The support for buffer exports in VA-API was added in version 0.36. These
interfaces are for interop with EGL, OpenCL, etc.

GStreamer-VAAPI uses it for a dmabuf memory allocator. Though, gstreamer-vaapi
has to support VA-API versions ranging from 0.30.4, which doesn't support it.

This patch guards all the buffer exports handling (and dmabuf allocator) if
the detected VA-API version is below 0.36.
