Adjust busybox defconfig to remove options that don't build under knoppix 5.1.1 (inotifyd, 2.4 module support) and yank options we don't want anyway because another package must provide them (patch, /bin/sh). (Pondered moving to a miniconfig, but this is still "almost defconfig" and the patch makes it easier to see what actually mattered to us.)
