s3-libnet_join: allow fallback to NTLMSSP auth in libnet_join
When a non-DNS and non-default admin domain is provided during the join
sometimes we might not be able to kinit with 'user@SHORTDOMAINNAME'
(e.g. when the winbind krb5 locator is not installed). In that case lets
fallback to NTLMSSP, like we do in winbind.
