Gerald Combs 30c392f166 Tools+test: Call python3 explicitly.
PEP 394[1] says,

"In cases where the script is expected to be executed outside virtual
 environments, developers will need to be aware of the following
 discrepancies across platforms and installation methods:

  * Older Linux distributions will provide a python command that refers
    to Python 2, and will likely not provide a python2 command.

  * Some newer Linux distributions will provide a python command that
    refers to Python 3.

  * Some Linux distributions will not provide a python command at all by
    default, but will provide a python3 command by default."

Debian has forced the issue by choosing the third option[2]:

"NOTE: Debian testing (bullseye) has removed the "python" package and
 the '/usr/bin/python' symlink due to the deprecation of Python 2."

Switch our shebang from "#!/usr/bin/env python" to "#!/usr/bin/env
python3" in some places. Remove some 2/3 version checks if we know we're
running under Python 3. Remove the "coding: utf-8" in a bunch of places
since that's the default in Python 3.
