evaluate: merge nested set flags

A set may contain a nested set element definition, merge the nested set
flags so we don't hit:

 BUG: invalid data expression type range
 nft: netlink.c:400: netlink_gen_data: Assertion `0' failed.
 Aborted

With the following example ruleset:

 define dnat_ports      = { 1234-1567 }
 define port_allow      = {
        53,             # dns
        $dnat_ports,    # dnat
 }

 add rule x y tcp dport $port_allow accept
