vaapipostproc: use GstBuffer flags for TFF.

Browse source 
Determine whether the buffer represents the top-field only by checking for
the GST_VIDEO_BUFFER_TFF flag instead of relying on the GstVaapiSurfaceProxy
flag. Also trust "interlaced" caps to determine whether the input frame
is interleaved or not.
