[18/20] SPECfile cleanup - make sure the target directory exists
The 'mv' command failed after the last commit, beacuse the line
| install -p -m 644 -D selinux/%{pkg_name}-server-galera.pp %{buildroot}%{_datadir}/selinux/packages/targeted/%{pkg_name}-server-galera.pp
which was originally before the cracklib condition, created the target directory tree thanks to the
| install -D
functionality.
