 - Issue #11133: fix two cases where inspect.getattr_static can trigger code
 execution. Patch by Daniel Urban.

 - Issue #11501: disutils.archive_utils.make_zipfile no longer fails if zlib is
 not installed. Instead, the zipfile.ZIP_STORED compression is used to create
 the ZipFile. Patch by Natalia B. Bidart.
