dev-libs/keybinder-0.3.1-r201: drop IUSE=lua support

An ancient version only kept in the tree because it's a dependency
of lxde-base/lxpanel, newer versions do not bundle Lua bindings any
more. No point in migrating this to Lua eclasses.

Committed with maintainer's permission obtained on IRC.

Closes: https://bugs.gentoo.org/752585
