[RFC PATCH v2] fix: rebuild rootfs on change of USERS

["'Clara Kowalsky' via isar-users" <isar-users@googlegroups.com>]

In case a change to the Isar created users is done, this currently
only re-triggers the do_rootfs_postprocess task. This task changes the
rootfs (e.g. home dirs are moved) and by that needs to operate on a
clean one. Otherwise old homedirs might still remain in the final rootfs
or move operations are not possible.

We fix this by ensuring that the do_rootfs_install task is executed
whenever a change to USERS is done. By that, we enter the
do_rootfs_postinstall with a clean rootfs.
