settings: drop unmaintained ifnet settings plugin of Gentooth/setting-plugin-ifnet

Even Gentoo disables this plugin since before 0.9.8 release
of NetworkManager. Time to say goodbye.

If somebody happens to show up to maintain it, we may resurrect it
later.

If "$distro_plugins=ifnet" was set, configure.ac would use that
to autodetect --with-hostname-persist=gentoo. Drop that autodetect
part too.
