systemd: fix tmpfiles location when multilib in use
Systemd's configuration files for creation, deletion and cleaning
of volatile and temporary files are installed in /usr/lib even when
multilib is in use (when /usr/lib64 is available). In this check the
systemd.conf file will not be found if libdir is /usr/lib64 so we fix the
path to match this file's installation path to look for it in
${exec_prefix}/lib
