[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=c53a26d866cd628c835a48056fb074aaf651bd57
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.11.x

keymaps and save-keymaps require kbd_mode and dumpkeys, respectively, so
remove them if the kbd package is not selected (e.g. devices with serial
console, only).
