package/criu: remove package

The criu package was added in Nov 2023, and then bumped once in
December 2023. Since then, it has never been bumped again, and all
follow-up fixes were provided by other people than the original
package submitter listed in the DEVELOPERS file.

criu has seen several upstream releases since then, and most notably
is causing a number of build issues in our autobuilders:

  https://autobuild.buildroot.net/?reason=criu-3.19

The package was never updated to those newer upstream releases, and
the autobuilder issues have not been addressed.

Therefore, let's drop this package.
