Replace the @PYTHONSHEBANG@ substitution with a valid #!/usr/bin/python3 shebang. This turns Python .in files into valid Python files. The files can now be checked with pylint and IDEs recognize the files as Python files. The shebang is still replaced with "#!$(PYTHON) -E" to support platform-python.
