Python venv does not copy the activate scripts

[Eric-rannaud]

According to the doc https://docs.python.org/3/library/venv.html

  python3 -m venv venv

Should copy the /usr/lib/python3.6/venv/activate* scripts into the venv/bin/ directory, so that they can be sourced by the user.

After running venv as above,

  venv/bin/python --version

works as expected. But venv/bin/activate is missing.

The same works correctly on Arch Linux.
