Add PAL_PYTHON.cpython-VERSION-ARCHITECTURE.so

[physar]

Currently only the Ubuntu-18.04 branch has a PAL_PYTHON.cpython library.

https://github.com/DreamVu/PAL-USB/tree/Ubuntu-18.04/lib

The same library is needed for the other distributions

https://github.com/DreamVu/PAL-USB/tree/Ubuntu-16.04/lib https://github.com/DreamVu/PAL-USB/tree/Ubuntu-18.04-GPU/lib https://github.com/DreamVu/PAL-USB/tree/Ubuntu-20.04/lib

Note that the default python is

• for Ubuntu 16.04 is python3.5,
• for Ubuntu 18.04 is python3.6,
• for Ubuntu 20.04 is python3.8,

• and Ubuntu 22.04 python3.10

  This is important because the python-version is the VERSION needed in PAL_PYTHON.cpython-VERSION-ARCHITECTURE.so
