st/va: set the visible image dimensions in vlVaDeriveImage

This fixes video being rendered incorrectly.

User wants height of 360 but internally pipe_video_buffer 's height
is 368 in the test below.

Test:
  GST_GL_PLATFORM=egl gst-launch-1.0 videotestsrc ! video/x-raw, width=868, height=360, format=NV12 ! vaapipostproc ! glimagesink
