Some Avocado-based tests use the "archive" module from avocado.utils to extract files from an archive. To be able to use these tests without Avocado, we have to provide our own function for extracting files. Fortunately, there is already the tarfile module that will provide us with this functionality, so let's just add a nice wrapper function around that. Reviewed-by: Daniel P.
