Helper script fails to launch stegosuite application

[David Dombrowsky]

The script in /usr/bin/stegosuite does not quote the arguments properly, making it impossible to embed messages with spaces in them:

```
stegosuite -e --message "a b c" foo.png
```

This can be fixed by properly quoting the arguments in the helper script. See this diff:

Thanks for your report. This was already fixed with Stegosuite 0.9.0.
You can get it if you update to Ubuntu 23.04 or newer. Or by downloading it from here: https://launchpad.net/ubuntu/+source/stegosuite/0.9.0-1/+build/24622575

You need libpicocli-java 4.6.2 or newer in order to run it (https://packages.ubuntu.com/kinetic/all/libpicocli-java/download)
