Merge: contrib/inkscape_tools: use Tinks! art instead of Dino's to test args

Fix #1657, it was actually the test that was broken as the SVG source file is designed for the bash script that preceded inkscape_tools and not inkscape_tools itself (see examples/mnit_dino/tools/). This PR use Tinks! art instead of Dino's. It was already tested by the Tinks! project but here we use it to test the program arguments.
