From: Jackie Huang <jackie.huang@windriver.com>

A race condition can occur when adding users and groups to the
passwd and group files, in [YOCTO #1794], 10 times retry added
but it is not fixed completely.

This fix re-writes the useradd_preinst and useradd_sysroot with
python and use locking of bb.utils to lock the passwd and group
files before executing useradd/groupadd commands to avoid the
lock race themselves.

[YOCTO #2779]
