The new test cases revelead the following bugs:

    FAIL!  : ExtractTest::testPreservePermissions(test preserve 0664 permissions (7z, kerfuffle_cli7z)) Compared values are not the same
    FAIL!  : ExtractTest::testPreservePermissions(test preserve 0664 permissions (tar.gz, kerfuffle_libarchive)) Compared values are not the same
    FAIL!  : ExtractTest::testPreservePermissions(test preserve 0755 permissions (zip, kerfuffle_libzip)) Compared values are not the same
    FAIL!  : ExtractTest::testPreservePermissions(test preserve 0664 permissions (zip, kerfuffle_libzip)) Compared values are not the same
    FAIL!  : ExtractTest::testPreservePermissions(test preserve 0664 permissions (zip, kerfuffle_cli7z)) Compared values are not the same

In the libzip case, we need to retrieve the permissions from the
extended file attributes.
