bitbake: tests/parse: Add BBCLASSEXTEND multiple data store corruption reproducer
One data store changing a variable poked through into a different data store. This test case replicates that issue where the value 'B' would become unset/disappear. We also enhance parsehelper to generate files with an optional suffix such as bbclass.
