Using stub_template.txt as __main__.py and zip header in python executable zip

In stub_template.txt, we now unzip the python zip file to a temp
directory if needed.
This will get rid of bash in python executable file completely.

Users can run the binary directly or using python <zip>, like:
    ./bazel-bin/examples/py_native/bin
or  python ./bazel-bin/examples/py_native/bin

On Windows, we can use the second way to run python binary from native
Windows command line (cmd.exe).
