Improve installation of Python packages

[jesper-friis]

Description

Improve installation of Python packages and include the following in the distribution:

• utility programs like dlite-getuuid, dlite-codegen, patch-activate.sh
• storages, like blob.json
• README.md and LICENSE files

In addition it fixed a bug in the setup.py script that in addition to dlite-python also installs a pip package called dlite. If you remove that you will remove pip, hense messing with your entire environment.

---

The changes can be tested locally with

cd python
python setup.py bdist_wheel

and then install the wheel with pip in a newly created environment

pip install dist/DLite_Python-0.5.22-cp310-cp310-linux_x86_64.whl

After that, you should be able to import dlite in the standard manner

python
>>> import dlite
