Remove unmaintained experimental tools

The kmod insert/remove tools were introduced back in 2015. Since then
they have recieved zero attention, unlike the insmod/rmmod variants.

Glancing around - neither of the following distributions (Arch, Fedora,
Gentoo, Debian) build them, so we're safe to say they have no users.

Remove them and alongside it the --enable-experimental toggle, which no
longer controls anything.
