Removes old screenshots

Merged Martin Jirku requested to merge harryjrk/gnome-maps:351-remove-old-jpgs into master

We have old jpg screenshots in the repo valid only for <=3.30.x releases, which were replaced by *.pngs. It's safe to remove them now to shave off some space from tarballs. Implements #351 (closed)

Closes #351 (closed)
