Tree-wide use of python3HEADmaster

It seems that unversioned Python shebangs are discouraged these days:

- See the lintian web on Debian:
  https://lintian.debian.org/tags/script-uses-unversioned-python-in-shebang.html

- Also, see "Finalizing Fedora's Switch to Python3":
  https://fedoraproject.org/wiki/FinalizingFedoraSwitchtoPython3

Replace them all tree-wide.

  CPython bindings are available for nftables under the py/ folder.  They can be
  installed using pip:
 
-	python -m pip install py/
+	python3 -m pip install py/
 
  A legacy setup.py script can also be used:
 
-	( cd py && python setup.py install )
+	( cd py && python3 setup.py install )
 
  However, this method is deprecated.
