[Buildroot] [PATCH 03/11] package/python-crccheck: new package

[Thomas Petazzoni]

This commit adds a new host only package for the crccheck Python
module, which is a dependency of Snagboot.

Homepage on PyPi: https://pypi.org/project/crccheck/

This commit also adds a very basic test case that allows to verify
that the Python module can be imported and that some minimal
functionality works.
