net-firewall/ipset: Support mod buildn,mig to linux-mod-r1,add myself

A user has request we add back support for ipset module building.
The specific use case was around supporting embedded, as older
kernels are consider quite up to date.

Add myself as maintainer

Fix extraneous echo

Closes: https://bugs.gentoo.org/908698
