Andrii Nakryiko eceae70bde selftests/bpf: Fix invalid use of strncat in test_sockmap
strncat()'s third argument is how many bytes will be added *in addition* to
already existing bytes in destination. Plus extra zero byte will be added
after that. So existing use in test_sockmap has many opportunities to overflow
the string and cause memory corruptions. And in this case, GCC complains for
a good reason.

Fixes: 16962b2404 ("bpf: sockmap, add selftests")
Fixes: 73563aa3d9 ("selftests/bpf: test_sockmap, print additional test options")
Fixes: 1ade9abadf ("bpf: test_sockmap, add options for msg_pop_data() helper")
Fixes: 463bac5f1c ("bpf, selftests: Add test for ktls with skb bpf ingress policy")
Fixes: e9dd904708 ("bpf: add tls support for testing in test_sockmap")
Fixes: 753fb2ee09 ("bpf: sockmap, add msg_peek tests to test_sockmap")
