src: add support for setting secmark
Add support for new nft object secmark holding security context strings.
The following should demonstrate its usage (based on SELinux context):
# define a tag containing a context string
nft add secmark inet filter sshtag \"system_u:object_r:ssh_server_packet_t:s0\"
nft list secmarks
# set the secmark
nft add rule inet filter input tcp dport 22 meta secmark set sshtag
# map usage
nft add map inet filter secmapping { type inet_service : secmark \; }
nft add element inet filter secmapping { 22 : sshtag }
nft list maps
nft list map inet filter secmapping
nft add rule inet filter input meta secmark set tcp dport map @secmapping
[ Original patch based on v0.9.0. Rebase on top on git HEAD. --pablo ]
