Add missing applets used by init scripts: printf, readlink, test, true, false, which, free, pidof, insmod, modprobe, lsmod, ifconfig, ip, route, uptime, lsblk, zcat, gunzip, gzip, xz, unxz, du, df, id, ash, halt. QEMU-verified: init script runs to completion with working busybox, hiperiso banner displays, all kernel cmdline params parsed correctly, data partition detected, shell prompt available.
