[OE-core] [PATCH 2/2] useradd.bbclass: remove user/group created by the package in cleanall task

[Maxin B. John]

At present, if a recipe is built which creates users/groups via useradd.bbclass,
those users/groups are not removed (at least from sysroot) when the
recipe/package is cleaned using cleansstate/cleanall.

This "userdel_sysroot_sstate()" provides that functionality. Please note
that this function does not affect the users/groups created in the final
root filesystem.

[YOCTO #9262]
