Title of the patch: Security update for apptainer
Description of the patch: This update for apptainer fixes the following issues: Changes in apptainer: - Update to version 1.5.3: * If the ptrace() system call does not work while building an image as an unprivileged user, skip using PRoot to preserve file ownership and print an INFO message. * Bind getopt from the host when using fakeroot command mode, to make the fakeroot command work with base containers which no longer contain getopt by default. * Update fixes CVE-2026-56852 (GO-2026-5970) (bsc#1272115) golang.org/x/text/unicode/norm: A norm.Iter can enter an infinite loop when handling input containing invalid UTF-8 bytes. - Update to version 1.5.2: * Extended the mksquashfs segmentation fault workaround for cases where mksquashfs uses many processor cores. - Update the golang.org/x/net dependency to version v0.57.0 to fix CVE-2026-39821 for good (bsc#1266656). The fix in v0.55.0 only applied to Unicode versions >=16.0.0 which aren't yet available on any Golang versions released.

For example, a program which performs privilege checks on the ASCII hostname may reject \"example.com\" but permit \"xn--example-.com\". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name \"example.com\".",
