[glibmm/glibmm-2-64] tools/defs_gen/*.py: Specify that this is python3 code

commit b5c531656d4a60e5bbb83ec1e0934191b91ce390

    tools/defs_gen/*.py: Specify that this is python3 code
    
    Specify #!/usr/bin/env python3, making it unnecessary to have a python
    command which is a link to python3.
    In h2def.py, use the built-in set() instead of Set() from the sets module.
