gst-libav: avvideocompare add video meta in alloc query
Fixes issue described in:
cc: @tpm
Silly mistake! I removed this line that adds the video allocation meta when I updated it to pass through pools and allocs from downstream
☹ The removal caused a regression in one of our internal BAT test cases in gstreamer-vaapi on older Intel platforms (vid->sys copy not triggered... so buf padding created problems?). This was captured when reconciling our cartwheel repo after this merged https://github.com/intel/cartwheel-gstreamer/pull/60.
I will submit a new MR here that reinstates this line... and fixes the issue (without new regressions). I have already added the fix to our cartwheel repo in https://github.com/intel/cartwheel-gstreamer/pull/60.
