python3: Fix of 2 CVEs
- CVE-2026-0864: normalize all line endings (CR, CRLF, and LF) in configparser to prevent key/value injection when writing multi-line values - CVE-2026-11940: fix symlink escape via the tarfile hardlink-extraction fallback by validating the symlink at the path it is recreated at, and route the extraction filter through TarFile.extract() so single-member extraction is covered by the check and not only extractall()
