[PATCH nft 2/2] src: secmark: fix missing quotes in selctx strings output

[Eric Jallot]

Colon is not allowed in strings and breaks nft -f.
So move to quoted string in selctx output.

Before patch:
 # nft list ruleset > rules.nft; cat rules.nft
 table inet t {
         secmark s {
                 system_u:object_r:ssh_server_packet_t:s0
         }
 }
 # nft flush ruleset
 # nft -f rules.nft
 rules.nft:3:11-11: Error: syntax error, unexpected colon
                system_u:object_r:ssh_server_packet_t:s0
                        ^

After patch:
 # nft list ruleset > rules.nft; cat rules.nft
 table inet t {
         secmark s {
                 "system_u:object_r:ssh_server_packet_t:s0"
         }
 }
 # nft flush ruleset
 # nft -f rules.nft
