tests/plugins/pip-samples/sample-plugins: Adding a sample pip plugins package

This commit:

  * Adds a bare bones BuildStream pip plugin package structure at
    tests/plugins/pip-samples/sample-plugins

  * setup.cfg: Adds tests/plugins/pip-samples to the norecursedirs so that
    we don't consider the dummy plugins as test code
