tc: flower: fix output for ip tos and ttl 

Fix the output for ip tos and ttl to be numbers in JSON format.

Example:
$ tc qdisc add dev eth0 ingress
$ tc filter add dev eth0 protocol ip parent ffff: prio 1 flower skip_hw \
      ip_tos 5/0xf action drop

Non JSON format remains the same:
$ tc filter show dev eth0 parent ffff:
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1
  eth_type ipv4
  ip_tos 5/0xf
  skip_hw
  not_in_hw
        action order 1: gact action drop
         random type none pass val 0
         index 1 ref 1 bind 1

JSON format is changed (partial output):
$ tc -p -j filter show dev eth0 parent ffff:
Before:
        "options": {
            "keys": {
                "ip_tos": "0x5/f",
                ...
After:
        "options": {
            "keys": {
                "ip_tos": 5,
                "ip_tos_mask": 15,
                ...
