[PATCH 2/2] scripts: Add spdxcheck.py self test

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

Add a script that will run spdxcheck.py through a couple of self tests
to simplify validation in the future. The tests are run for both Python
2 and Python 3 to make sure all changes to the script remain compatible
across both versions.

The script tests a regular text file (Makefile) for basic sanity checks
and then runs it on a binary file (Documentation/logo.gif) to make sure
it works in both cases. It also tests opening files passed on the
command line as well as piped files read from standard input. Finally a
run on the complete tree will be performed to catch any other potential
issues.
