sss_parse_inp_send: provide default_domain as parameter
It is not always desirable to consider default_domain from configuration
but expect none instead. For example when we search host certificates.
This is currently not used in this patch since host lookups parse
name directly with sss_parse_name but it will be used in the next
patch.
