Replace the trivial setup.sh system test files

Replace the trivial setup.sh system test files

All these setup files only use copy_setports function which can be done
with jinja2 templates instead -- simply by renaming the .in files to
.j2, without any other changes. The pytest runner will render these
templates during test setup without any need for an additional script.
