Fix python package steps

[chefren]

In the creating a package for function with dependencies (ref), the command series to create the package do not work

Steps to reproduce

Following the same steps as the current docs

• pip install --target ./package requests
• zip -r my-deployment-package.zip ./package/

Produce a zip file with the "package" folder containing the dependencies

unzip -l my-deployment-package.zip
Archive:  my-deployment-package.zip
  Length      Date    Time    Name

Therefore the following python module lambda_function.py is unable to do import requests once loaded to lambda.

import requests

def lambda_handler(event, context):
    print("Test")

Testing produces

[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function': No module named 'requests'

Fix

• As per man zip the only option to discard paths (-j) discards all and is not proper
• The same steps are proposed as for virtualenv to fix this (ref)
