The below path error can occur:
# ./xdp2skb_meta.sh --dev eth0 --list
./xdp2skb_meta.sh: line 61: /usr/sbin/tc: No such file or directory
So just use command names instead of absolute paths of tc and ip.
In addition, it allow callers to redefine $TC and $IP paths
Fixes: 36e04a2d78 ("samples/bpf: xdp2skb_meta shows transferring info from XDP to SKB")
