vaapipostproc: add initial support for GStreamer 1.2.
Port vaapipostproc element to GStreamer 1.2. Support is quite minimal right now so that to cope with auto-plugging issues/regressions. e.g. this happens when the correct set of expected caps are being exposed. This means that, currently, the proposed caps are not fully accurate.
