This patch lays the groundwork for testing IPv4 and IPv6 sockaddr hooks and their interaction with both socket syscalls and kernel functions (e.g. kernel_connect, kernel_bind, etc.). It moves some of the test cases from the old-style bpf/test_sock_addr.c self test into the sock_addr prog_test in a step towards fully retiring bpf/test_sock_addr.c. We will expand the test dimensions in the sock_addr prog_test in a later patch series in order to migrate the remaining test cases.
