criu: Version 4.1.1

This release of CRIU (4.1.1) addresses a critical compatibility issue
introduced in the Linux kernel and back-ported to all stable releases.

The kernel commit (12f147ddd6de "do_change_type(): refuse to operate on
unmounted/not ours mounts") addressed the security issue introduced
almost 20 years ago. Unfortunately, this change inadvertently broke the
restore functionality of mount namespaces within CRIU. Users attempting
to restore a container on updated kernels would encounter the error:
"mnt-v2: Failed to make mount 476 slave: Invalid argument."

This release contains the necessary adjustments to CRIU, allowing it to
work seamlessly with kernels incorporating this security change.
