lavc/videotoolbox: Fix cropping with HEVC and H264 videos 

videotoolbox returns an already cropped stream which led to double
cropping. this issue was introduced with the refactor of the cropping
mechanism in commit 07596e4 for h264 and 000fb61 for HEVC.

to fix this we set the cropping of the frame and the output frame to 0.

Tested-by: ponpon
Fixes ticket #7544.
