selftests/bpf: fix -Wstrict-aliasing in test_sockopt_sk.c
Let's use union with u8[4] and u32 members for sockopt buffer,
that should fix any possible aliasing issues.
test_sockopt_sk.c: In function ‘getsetsockopt’:
test_sockopt_sk.c:115:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
if (*(__u32 *)buf != 0x55AA*2) {
^~
test_sockopt_sk.c:116:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
log_err("Unexpected getsockopt(SO_SNDBUF) 0x%x != 0x55AA*2",
^~~~~~~
Fixes: 8a027dc0d8f5 ("selftests/bpf: add sockopt test that exercises sk helpers")
