Remove the --no-sssd option from ipa-client-automount
    
    This makes automount configurable only using sssd and not LDAP.
    The reason is that authselect 1.3 no longer supports
    user-nsswitch.conf which is where we made direct changes to the
    nss configuration on Fedora/RHEL.
    
    The equivalent option was removed from ipa-client-install in
