Add busybox patch that allows to install all utilities under /usr/bin

As part of tsc#73 (closed) we decided to move every busybox utility under /usr/bin. There is already the config option INSTALL_NO_USR. ncopa had the idea to add something like INSTALL_USR_BIN that ensures all binaries to to /usr/bin. Alpine needs this (unlike other distros) because Alpine has this magic with replacing busybox programs with “proper” programs if you install e.g. coreutils. This probably means also fixing package of every package that busybox can replace
