- Rewrite the script to Python:
* the current script is quite slow and delays libreoffice package
build where we install all packages and then uninstall them
* the script uses linkfile=${file/${datadir}/${libdir}} for replacement
of $datadir prefix with $libdir (if the $file path starts with $datadir;
if not, we end up with an empty string and we execute various shell
scripts with it
* the Python implementation should be more readable
* the Python version runs about 200s faster when it comes to libreoffice
package build (on a recent Ryzen 9 machine)
