UnicodeDecodeError: utf-8 on python semanage -i import

[Allan Oepping <allan@xxxxxxxxxxxxxx>]

Importing a .pp file with the python semanage -i option generates a "UnicodeDecodeError: utf-8" on an up to date Rocky 9 distribution.

packages:

policycoreutils-python-utils-3.6-2.1.el9.noarch
python-unversioned-command-3.9.18-3.el9.noarch

The open() in SetImportFile needs the binary "b" option to open the file in binary mode, as the .pp file is not in utf-8 format:

patch also attached.
