test: Move unit tests below jw/pkg

Move the unit test hierarchy to below test/unit/python/jw/pkg. Nesting the subdirectories so deeply might be overly careful, but it may as well be not - maybe in the future installable test packages are going to be generated and need simple ways to install without stepping onto each other's toes. If not, it's easier to cut two directory components out than having to reorganize possibly incoherent paths grown over multiple packages.
