Fix support for nss-pam-ldapd

Client installation with --no-sssd option was broken if the client
was based on a nss-pam-ldap instead of nss_ldap. The main issue is
with authconfig rewriting the nslcd.conf after it has been
configured by ipa-client-install.

This has been fixed by changing an order of installation steps.
Additionally, nslcd daemon needed for nss-pam-ldap function is
correctly started.
