Consider patool test suite for extractcode

[pombredanne]

See https://github.com/wummel/patool/tree/master/tests/data for more tests cases.

@pombredanne i would like to work on this issue.

I've just created a PR aboutcode-org/scancode-toolkit#546 for a single test case from the patool test suite to check if this is the right of implementing a new test case. If everything checks out I will work on adding more test cases.

@michaelrup great PR, and this is the right approach alright. Since in this case we borrow test archives files, we just need to credit @wummel and make sure we handle these properly as GPL-licensed test files from https://github.com/wummel/patool as I explained in aboutcode-org/scancode-toolkit#546 (review)

@wummel: just a heads up @michaelrup is adding new tests for scancode's own extraction code using your own test archives for patool.

@michaelrup any plan for you to add more tests to this?
