CI: AppImage support

 - Add a script for building a Calamares AppImage file (this is
   useful in *some* limited contexts, not a general way to distribute
   Calamares since it's much more efficient to use installed libs).
 - Add example config files for this AppImage build.
 - Download the linuxdeploy tools if they are missing
 - Document script flags some more
