[OE-core] [PATCH 1/1] libpam: add system-auth in case of systemd

[Chen Qi]

systemd needs this file to be there because one of its configuration file
in pam.d, systemd-user, requires it. Otherwise, we would have errors like
below.

    systemd: PAM _pam_load_conf_file: unable to open /etc/pam.d/system-auth
