python3: add new files to compression

As of Python 3.14, there is a new top-level compression module that
contains the gzip and tarfile modules from previous versions, along with
a new _common module. However, for compatibility reasons the project is
also leaving a copy of the gzip and tarfile modules in the original
positions (to be handled in a future deprecation cycle).
