Fix presentation sizes for CTS video assets.

There appears to be a bug in ffmpeg that sets the presentation size for the video
(a header field that specifies the size of the frame that the window should be
presented in) based on the original video's aspect ratio, ignoring -cropleft
and -cropright which change the aspect ratio.  So, this tweaks the presentation
sizes to match the video content, allowing this test to pass no matter how the
size is calculated.

Commands run:

for file in `ls *176x144*`; do xxd $file | sed 's/00000e0:\([0-9 ]*\)0100 0000/00000e0:\100b0 0000/' | xxd -r  > $file.tmp && mv $file.tmp $file; done
for file in `ls *480x360*`; do xxd $file | sed 's/00000f0: 0280 0000/00000f0: 01E0 0000/' | xxd -r  > $file.tmp && mv $file.tmp $file; done
