[OE-core] [PATCH] shadow: fix pam configs for chpasswd, newusers

[Hongxu Jia]

From: "yadi.hu at windriver.com" <yadi.hu at windriver.com>

While pam is enabled:
...
DISTRO_FEATURES_append = " pam"
...

Fix below errors on target:
...
  root at qemux86:~# newusers
  newusers: PAM: Authentication failure
  root at qemux86:~# chpasswd
  chpasswd: PAM: Authentication failure
...

The configs copied from "chgpasswd" which command works with pam.
