[Buildroot] [PATCH 2/4] support/testing/tests/package/test_python_flask: new test

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

This commit adds a test for python-flask package. As we are about to
add python-flask-expects-json together with a test, it made sense to
also add a test for python-flask itself.

As far as the DEVELOPERS file is concerned, the test files are added
both to the existing maintainer of package/python-flask, as well as to
myself.
