Don't install example scripts

[jodal]

Currently, the scripts/ directory of hbmqtt is installed as the very generically named scripts Python module.

This can be avoided by either:

A) making the scripts directory not be a Python module by removing the __init__.py file, or

B) add scripts to the excludes parameter of find_packages() in setup.py.

Since the there is no reason the scripts directory needs to be a Python module, I went with A.

Demonstration of the issue without this fix:

$ mktmpenv -p /usr/bin/python3
Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/jodal/dev/virtualenvs/tmp-329f000d98121a91/bin/python3
Also creating executable in /home/jodal/dev/virtualenvs/tmp-329f000d98121a91/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
This is a temporary environment. It will be deleted when you run 'deactivate'.
