Add json output support for checksum action.
Example output:
~$ $TC actions add action csum udp continue index 7
~$ $TC actions add action csum icmp iph igmp pipe index 200 cookie 112233
~$ $TC -j actions ls action csum
[{
"total acts":2
}, {
"actions": [{
"order":0,
"csum":"udp",
"control_action": {
"type":"continue"
},
"index":7,
"ref":1,
"bind":0
}, {
"order":1,
"csum":"iph, icmp, igmp",
"control_action": {
"type":"pipe"
},
"index":200,
"ref":1,
"bind":0,
"cookie":"112233"
}]
}]
v2:
Don't initialized char buf[64];
Add output example

Looks good.
In iproute2 the common macro for declaring these kind of buffers is:
SPRINT_BUF(buf);
Doesn't matter that much, but nice to have consistency.

changed that line to 'SPRINT_BUF(buf);' per Stephen's comment and
applied to iproute2-next.
