python: upgrade to version 3.4.1

python: upgrade to version 3.4.1

Some notes:
- Python 3 (at least version 3.4) is pretty cross-compiler-friendly,
  so a lot of patches were thrown away.
- Arguments below were moved to ./files/config.site file, and disabled
      ac_cv_have_chflags=no \
      ac_cv_have_lchflags=no \
      ac_cv_py_format_size_t=no \
      ac_cv_have_long_long_format=yes \
      ac_cv_buggy_getaddrinfo=no \
- --without-ensurepip added, because the build wants to ensure that
  it works; that's a good idea, but for now, it requires special
  setup, and we can do that later
- --without-pymalloc added, becase in Python 3, modules are suffixed
  with m; e.g. so some paths are python3.4m instead of python3.4
  all this is detailed here:
         http://legacy.python.org/dev/peps/pep-3149/
  Maybe it will be a good idea to re-add this back
