I think this is caused by a change in iputils_3:20240905-1 and has
nothing to do with perl, except that the perl migration checks fall
back to pulling all dependencies from unstable (including iputils-ping)
because of autopkgtest limitations.

This is backed by the iputils migration checks, where backuppc is failing
in the same way with just iputils from unstable.

Reassigning. Hope I got the syntax right.
