releasetools: Don't return ZipFile from common.UnzipTemp().
In addition to the unzipping work, common.UnzipTemp() kindly bundles an open ZipFile object as part of the return value. It doesn't look very helpful to the callers though. It also looks less obvious that the caller needs to properly close the handle (missing the close here is benign though). This CL just removes the ZipFile object out of the return value, and leaves the work to callers. Test: `m dist` on both of A/B and non-A/B target. Test: python -m unittest test_add_img_to_target_files Test: python -m unittest test_common Test: python -m unittest test_ota_from_target_files Test: Check the callers to common.UnzipTemp() in code search.
