python3-license-expression: fix ptest installation

This recipe was overriding do_install_ptest which is provided by the
ptest-python-pytest class, so there was no tests or run-ptest installed.

Use an append override, and minimise the installed files: use a symlink
so that scancode-licensedb-index.json is found and install setup.cfg.
