Actually, I found that forcing the pixel-aspect-ratio downstream can be
used to work around the problem. I skeptical on how this aspect ratio is
being computed. This pipeline works for me:

gst-launch-1.0 videotestsrc !
video/x-raw,width=352,height=288,aspect-ratio=1/1 ! videoscale
add-borders=1 !
video/x-raw,width=640,height=360,pixel-aspect-ratio=1/1 ! xvimagesink
