Remove nslcd and related packages on Debian

This is part of the change to replace nslcd with sssd to
support multiple secure ldap backends.

This change removed nss-pam-ldapd (nslcd, libpam-slapd,
libnss-slapd) on Debian based stx system.

nscd is removed in
https://review.opendev.org/c/starlingx/tools/+/854217

Test Plan on Debian:
PASS: Package build, image build
PASS: System deployment
PASS: Verify nslcd, libpam-slapd, libnss-slapd are not installed.
PASS: ldap functions work properly (ldap user creation, user login
      on console and by ssh etc).
