selftests: bpf: Less strict size check in sockopt_sk
Originally, the kernel strictly checked the size of the optval in getsockopt(TCP_ZEROCOPY_RECEIVE) to be equal to sizeof(struct tcp_zerocopy_receive). With c8856c05, this was changed to allow optvals of different sizes. The bpf code in the sockopt_sk test was still performing the strict size check. This fix adapts the kernel behavior from c8856c05 in the selftest, i.e., just check if the required fields are there.
