Subject: [PATCH] adduser: add -M option for useradd when --no-create-home is specified

The useradd (from package passwd) in debian based system sets -M (--no-create-home) by default,
but the one we are using (from package shadow) sets -m (--create-home) by default, so we
need to explicitly add -M option for useradd call when --no-create-home is specified for adduser.

Upstream-Status: Pending
