gnu: inetutils: Update to 2.4.

[Development of GNU Guix and the GNU System distribution.]

Hi,

With core-updates possibly being replaced by feature branches, I am
not sure where to place this update to GNU Inetutils 2.4.

The patch series [1] will rebuild 3,416 packages.

Thank you, everyone, for your hard work!

Kind regards,
Felix Lechner
