ldap: Pull nss-pam-ldapd into the openbmc image

Bringing the LDAP authentication module support in openbmc stack
requires to pull the nss-pam-ldapd which allows the LDAP
server to provide the user, passwd, group info that we normally get
from the /etc flat files.

nss-pam-ldapd provides libnss-ldap and pam_ldap module which
delegate the work to the nslcd(daemon) that queries the LDAP server.
pam_ldap uses the openldap client API to interact with the LDAP server.

nss-pam-ldapd files are pulled from
http://git.yoctoproject.org/cgit/cgit.cgi/meta-cloud-services/
tree/recipes-support/nss-pam-ldapd

meta-cloud-services sha: 38cc19fb3a813673051de314aafabda0545d8466

Tested: Adding the "ldap" distro feature brings the nss-pam-ldapd
and its dependencies into the image and removing the "ldap" from the
distro feature doesn't bring the nss-pam-ldapd and its dependencies.
