initscripts: Fix regression for requiring /bin/bash

It is not possible to create a rootfs with only busybox + initscipts.
This is a result of a regression from commit
a4b53872a8a9a2743299acbff015f7f2750a69d6 (initscripts: add
/sbin/sushell for systemd service debug-shell).

The /sbin/sushell should just use /bin/sh else you end up with a
problem when creating the end image with a failed smart transaction
shown below:
