Wrong shebang in waf

[ChthonVII]

Shebang in waf should say #!/usr/bin/env python3 rather than #!/usr/bin/env python.

Sorry, I no longer have time to maintain this project. It would be great if someone can submit a PR for this and I will happily merge it.

You can use the python-is-python3 package.

Description: symlinks /usr/bin/python to python3
Starting with the Debian 11 (bullseye) and Ubuntu 20.04 LTS (focal)
releases, all python packages use explicit python3 or python2
interpreter and do not use unversioned /usr/bin/python at all. Some
third-party code is now predominantly python3 based, yet may use
/usr/bin/python.
.
This is a convenience package which ships a symlink to point
the /usr/bin/python interpreter at the current default python3. It may
improve compatibility with other modern systems, whilst breaking some
obsolete or 3rd-party software.
