MDEV-37092 galera_new_cluster installed under WITH_WSREP=OFF

galera_new_cluster is a script intended solely for use with galera
and shouldn't be installed unless WITH_WSREP=ON.

In 11.6 the installation became part of scripts/CMakeList.txt
and no-longer had a WITH_WSREP=ON condition around installing this file.
The galera_new_cluster in systemd.cmake had no effect as the
script is a generated file and not in the source directory.

Changes:

The scripts/CMakeList.txt has a condition WITH_WSREP=ON for installing
the galera_new_cluster script.

The legacy reference in cmake/systemd.cmake is removed.

Thanks Michal Schorm for the bug report.
