kselftests/bpf: use ping6 as the default ipv6 ping binary when it exists 

At commit deee2cae27 ("kselftests/bpf: use ping6 as the default ipv6 ping
binary if it exists"), it fixed similar issues for shell script, but it
missed a same issue in the C code.

Fixes: 371e4fcc9d ("selftests/bpf: cgroup local storage-based network counters")
