[test] Replace symlinks in legacy_cubes by real copies
This solves a "python setup.py build" issue on my machine.
Copying these files should not be a big deal because they
have been dropped in the "default" branch and we would not
touch them in 3.26 branch.

rm -rf /etc/cubicweb.d/
rm -rf /var/log/cubicweb/
rm -rf /var/lib/cubicweb/
